You're own experience is exactly that. What I will say though Is that Easyjet's on time performance is now amongst the best out there. It is something like 84% for departures and higher for arrivals.
Although most stations handle speedy boarding well, certain destinations always can't seem to handle it. HAM yesterday for instance.... Usually an air bridge but couldn't handle it with bussing. Allocated seating is now looking very likely as I said.... Something Ryanair isn't offering.
Onboard prices.... Easyjet is expensive but on a par with other carriers pretty much. Ryanair on the over hand are definitely more expensive. A simple comparison of the sales brochure would show that.
