I don't comment in these threads often, but today I am in the mood to do it.
I've played and beaten 1 to 6, 9 and 10. Only ever played a little bit of 7 on an emulator because I couldn't warm up to that game. I have yet to buy 11, the main reason being the lack of a physical version in Europe; the other reason is that I have enough games to play as it is, so I didn't even take the plunge the last time there was a good discount on the digital version.
Mega Man 2 and 3 are top tier. 4, 9 and 10 rank a tier below; still good, but the formula had already grown stale by then. 5 and 6 are merely decent as they can't compensate for their staleness with good music like 4, 9 and 10 can. 1's game and level design is very hit and miss, so its value is mostly restricted to coming up with the overarching idea and framework for the series.
I'd expect 11 to fall either in the good or decent tier while 7 and 8 would most likely go in the same tier as 1, which is to say, I don't expect them to be fun to play, let alone replay.
EDIT: I voted for Mega Man 4 in the poll for the sake of being a contrarian to the obvious battle between 2 and 3.
