My first-ever scope was a Weaver K2.5. Later on I went to a K4. I horse-traded into a Vari-X II 3x9, and ever after was pretty happy. Back about ten years ago, from curiosity, I got a Simmons 44Mag; 3x10x44. It works okay, but doesn't do anything for me that the 3x9 didn't.
So by and large I'm uninterested in "bigger" or "better" than the old Vari-X II.
My basic limit is 500 yards. I don't shoot long-range targets or benchrest competition. Seems to me that's the arena for very-high magnification and large glass.
