Which one is the easiest to beat?

I enjoyed all 11 Mega Man games. But 6 has to be my favorite. I just really like the level designs and robot masters.

but i rage quitted at the yellow devil... f**ck that boss

I'm curious to hear from the mega man community rather than just gaming journalists who claim mega man 2 is the best because of nostalgia. I think mega man 2 is a fine game, but of the classic series its my personal least favorite. I think there's a lot of overlooked design flaws in mega man 2, everywhere from poor boss patterns to bad weapon balance to unfair level design. I know the game was rushed, but it feels like someone just equipped the metal blade for play testing and said it was fine....

MM2 is the most over rated game of all time. Its a broken mess with extremely questionable hit boxes and atrocious level design.
