S GrossSet-wise, totally the "hunt."
When I was doing my e90-1, it was one of the greatest feelings I've had in collecting. Then I got to 118/120 (JJ and Young/throw), and realized it was over. I did what I could do, and realized there was some $$ to use in another quest. Sold them, never felt bad (except for a few), and have great memories.
Boxing-wise, many have come and gone: t218, t220, e75, e76 (actually still own, would sell for my price 
), e77 (1 of 2, still own 1), e79, leaf, adevnture. All fun at the time.
I'm down to only two T9 (Jeanette and McFarland), and I don't know what will happen when I get them --- just tooooooo beautiful to part with.
My sub-sub set, T210-1 Savannah, isn't going anywhere, just means too much to me and was a tough adventure (although moving onto the rest of T210-1 is an exciting thought). And my T225-2 (18/25) just aren't available, so they'll be around for a time.
I guess it's a balance of many factors, but the "hunt" is the drive (at least for me).
