Our Verdict

BenQ TH671ST

Epson EpiqVision Flex CO-W01

The Epson EpiqVision Flex CO-W01 and BenQ TH671ST excel in different areas, although the BenQ is a bit better overall. The Epson is the far brighter projector as it's meant for use in bright offices with lots of light. Conversely, the BenQ has far superior contrast, making it the better choice to watch movies in a dark room. The BenQ is also a bit more colorful due to its wider color gamut, and it's much more accurate out of the box than the Epson.
