There was a long, long, long time I had been reading X-Men, just because I literally had every issue of Uncanny X-Men (v1) #30-something and up. No gaps. Includes #94, GSX #1...
So I kept reading for a long time - because I had such a solid run.

I wrote about it - and how I dropped UXM before V1 ended (somewhere in the 550's - and I think it ended around 600-something)

Then wrote how Bunn brought me back when I heard he was on Uncanny -

After that ended, it was what I needed to cease collecting.

Since then, I've only picked up X-Men Legends (1 and 2), plan to get 3 (and any issues the Simonson do) and see where that goes.
