The Epson Home Cinema 880 edges out the BenQ TH671ST with 3300 lumens versus 3000 and 6000-hour lamp life versus 4000 per Epson and BenQ specs. BenQ wins on short-throw flexibility for tight spaces while Epson handles standard rooms better per Wirecutter projector guides. This is a close call for most buyers but Epson takes the win on longevity metrics.
