Our Verdict
Epson EpiqVision Flex CO-W01
NexiGo PJ40 (Gen 3)
The Epson EpiqVision Flex CO-W01 is better than the NexiGo PJ40 (Gen 3), but they're quite different. The Epson is far brighter than the NexiGo, but its contrast is significantly worse. Thankfully, the Epson is also more colorful and is much more accurate out of the box. Unfortunately, the Epson's feature set is limited, as it doesn't come with any wireless or smart features, and it projects images in a 1280 x 800 resolution, which isn't optimal for content consumption. Ultimately, while the Epson is the better product, it also feels ancient compared to the more modern NexiGo.
