In terms of silver age stuff, the Roy Thomas issues from 55-66 (with Neal Adams art for 56-63 and 65) are very good although most of the.silver age stuff is mediocre.

Uncanny post Claremont is kind of a mindfield. I can't think of many great runs. The 90s had some good moments but everything crossed over with the other X-men book and the rest of the line so just buying the uncanny issues wouldn't be advised.
Most of the great 2000s runs took place in other x books
Claremont's first return was unbelievably bad. I haven't read the second one. (I read everything except 306 to around 470 but did read the first Claremont return and several issues before it. The Twelve and something about the High Evolutionary.)
A lot of people will tell you that his original run stopped being good at X issue, but for my money it was all good until Jim Lee started plotting them.
