Might I hazard a guess that you don't fly from Gatwick? When I worked for easyjet down there I averaged well over 685 hours a year. Now I'm at BA I'm averaging more like 825 block hours a year on short haul but obviously I do a lot more duty hours than I used to. I haven't met a 320 FO or Captain who's done less than 800 in the last 12 months.
Regardless of how the two airlines are perceived a lot of it will come down to where you are based with easyJet. That's what makes the comparison more complicated than certain people would like.
