Epson has a two year warranty Panasonic only warranties the projector for a total of 2000 hours (or two years, whichever comes first). As a result most fairly heavy users - all of us who watch TV, sports, and movies (gaming too), will run out of warranty before two years is up.

The Epson also supports anamorphic lens and has a lamp life of 4000hrs compared to no anamorphic lens support and a lamp life of 2000 hrs.
