Samsung S90D OLED
The Samsung S95C OLED and the Samsung S90D OLED are very similar, but there are some minor differences. The S90D has better processing, so there's less banding in colors and fewer artifacts present in low-quality content, and it does a slightly better job at upscaling low-resolution content. The S90D is also a tad brighter in HDR, so highlights pop a little bit more on it. However, the S95C comes with Samsung's Slim One Connect Box, so if you need a versatile way to plug in your devices, it's the better option.

Hi RocketSurgeon,
Thanks for your insightful reply. I’m glad you found the article informative!
Air fryers use a centrifugal style fan, pulling air through the center and expelling it radially and down towards the food. The desired air pattern is a vortex that is constantly circulating and heating the air as it passes through the heater (you may have seen marketing graphics showing this airflow). I agree that simulating or even just trying to record the airflow is a complex task. In theory, I also agree that a circular basket shape would promote this airflow pattern. In practice however, the food inside the basket creates so much obstruction that it’s hard to imagine anything other than a very turbulent flow. Manufacturers are more frequently choosing a square basket shape to maximize the surface area available - as opposed to growing the basket in height to save counterspace. A good example of a bad design would be the Dash 2qt Air Fryer; while it’s small capacity warrants a small surface area, the surface area could have been maximized instead of having a taller, narrower basket (it also has a circular basket shape and has some of the worst air frying performance we’ve tested).
As for preheating, I think it depends on preference. We tested our air fryers this way because during our research, we found that the majority of users do tend to preheat. The large drop you see in the temperature stability graph is partially due to the thermal mass of the air leaving the system upon opening, but it’s mostly due to adding the frozen food. If you didn’t add the food before reinserting the basket, the temperature recovery time would be a fraction of what it is. In addition, the metal basket and cooking tray are what retain most of the energy from the preheat. Notably, food sizzles immediately once it’s added to a preheated basket, which could produce crispier results by immediately transferring energy to the surface of the food, instead of gradually bringing the chamber and food up to temperature together.
I hope you find this information helpful.
Thanks! Tristan
Excellent article. As I read each section, I thought: “Well, what about … . ” And then you covered that topic in the following sections.
Except for - how does the shape of the air fryer affect its performance. Some have a smooth circular shape which I suspect is better than the rectangular ones. However, the almost infinite variations in shape would be time consuming to test and would probably involve complicated aerodynamics. I suspect the middle 85% of designs would perform so similarly that consumers would find other features more important (e.g., how does it look on my counter, was it discounted). We are still counting on you to identify extreme examples of poor design that overwhelm the positive features.
Please resolve the debate about preheating air fryers. Some say preheating is important. Others say don’t bother. It is obvious that pulling out the drawer to load food at the end of the preheat phase greatly offsets the benefit of preheating. Your graphs above show that temperature recovery can take a long time. Should we just load all food at the start? Or should we preheat only when food crispiness is essential - like french fries?
Yes, we once had a TO with convection, and as an experiment I bought a basket for it. Reheating results did improve when air could get all around the food, but nothing like the 451. But other new air-fryer/ovens seem to also produce fine results when air frying, according to the avalanche of recent reviews, and that’s why I hope for some actual objective lab tests that focus on actual comparison of the two types of appliance on this one specific task.
Hi rdclark,
Thanks for your insightful comment. You’ve highlighted an important point: toaster oven / air fryer combos are becoming very popular as the do-it-all countertop appliance. It raises a valid question about the necessity of a dedicated appliance when multifunctional ones are available.
The Ninja DCT-451 is especially interesting as, in its lower chamber, it houses a heating element right next to its fan - like an air fryer. Many toasters ovens simply add a fan to circulate air inside the cooking chamber, which is more akin to a conventional convection oven than an air fryer.
We’re also curious about their air frying performance, and diving into these products and questions would certainly be interesting and relevant for many people.
Thanks! -Tristan
I hope you will find a way to fit air-fryer/toaster ovens into your testing. Many publications review them simply as toaster ovens, never answering the critical question: how do they perform as air fryers when compared to dedicated ones? For example, we’ve been using a Ninja DCT-451, whose performance as an air fryer and as a toaster oven have been excellent. But would we be even happier with a dedicated air fryer for those specific foods that most benefit from this method?
I just got the George Foreman beyond grill and think it is pretty awesome. Able to do up to seven different cooking styles and I like the grilling feature as well as air frying. For $100 I think it’s a pretty good value I got it on sale and through eBay but I’m sure ninja makes a better air fryer / indoor grill. The unit is really basic you pick the style of cooking the time and the temperature and that’s it, your good to go. I like the deep non-stick basket which features a grill plate that’s removable and it’s just really nice instead of the air fryer / oven I had previously that was hard to keep clean. A real roach magnet. Bella makes a similar type but with a pull out drawer which is pretty cool that was my other option. I was able to air fry the normal fries and nugget type things but also able to cook a pork roast, grill hamburgers and I could fry in it basically all my breakfast and dinner was done in the George Foreman.
