Our Verdict
Lenovo Legion 5 Gen 6 15 (2021)
Dell Alienware m15 R3 (2020)
The Dell Alienware m15 R3 (2020) is better than the Lenovo Legion 5 Gen 6 15 (2021). The Dell is a more premium device with a sturdier build, a more comfortable keyboard, a more responsive touchpad, and a wider port selection. The Dell also has better display options, like a 1080p 300Hz and a 4k 60Hz OLED panel. The performance will depend on which configuration you get. The Dell has older CPU and GPU options, but it can perform just as well or better than the Lenovo, provided that you get a higher-end configuration with an NVIDIA GeForce RTX 2080.
