Epson Home Cinema 5050UB vs BenQ GV30

The Epson Home Cinema 5050UB is much better than the BenQ GV30, but they're completely different products. The BenQ GV30 is a small projector with an integrated battery, so it's very easy to carry around, but it offers inadequate image quality for watching movies. The Epson is a very large projector and is not meant to be carried around; it's meant for a fixed installation in a home theater scenario. It does have impressive image quality, dwarfing what the BenQ offers in that department.
