As a child of the 90's I grew up with the X-Men of the 90's and thus will always have fond memories of that era, but as I got older and found older books I also enjoyed the 80's X-Men and their spin offs ( New Mutants etc.)

80's - 90's
 
80's due to the emergence of X-Factor and the consequent big events the X-Men encountered during that era. Days of Future Past was also in the 80's I think.
90's was just a treat. X-Cutioner's Song, Fatal Attractions, Phalanx Covenant, AoA, Onslaught, Zero Tolerance, etc.

90s...i was growing up during that era, so it was my first taste of the X-Men. My dad brought home X-men #1 with all the Variant Covers and I was in trance with them. Ever since then I started to get into comics even tho my dad had a lot of old ones before hand. I think it was becuz of Jim Lee.

This! I was born in 82. Didn't read comics till the early 90's.  Was introduced to the X Men via the 90's cartoon.Pretty much 80's and 90's X Men is what I love. Really can't stand the 2000's era.

Australia to Jim Lee.

Give me 80's, I want my X-Men in Australia

@Rabbitearsblog: For the most part I agree with what you say. I think that the 80s and 90s X-Men stories, along with Joss Whedon's X-Men run, are the best X-Men stories I have ever read. Where I differ a little bit is that I actually do kind of like parts of Morrison's run, but it is nowhere near as great as the other eras that I have listed.  On a slightly related note, so far the only X-Men story of this decade that I have really enjoyed has been Remender's run on Uncanny X-Force.

90's all the way

I kind of cherry pick through them... 60's were fun. Giant Size(Can't remember the year of it) was my first X-men comic so yeah...

PAUSE. Am I supposed to be Mercedes? Banned.

@spidermonkey2099: Totally agree. Even after having read Morrison's run a good five or six times, I still feel like it doesn't really deserve the hype. 90s all the way.

I prefer what has been done since 2010

80s and 90s

Best times... just the right amount of action, power projections and ground breaking approaches to comic book art, stronger characterization, among others.

But this is the era when my favorite Rachel Summers came to be.
