I don't have much experience with steels, particularly the high end stainless steels, but these are my three in no particular order:
1. 1095 and 1095CV, they sharpen up to a very fine edge with very little effort and hold it long enough for me to not constantly (something like AUS8, maybe) be sharpening it and I really like a good patina
2. Sandvik 14C28N, it has better edge retention than 1095(CV) (at the hardnesses generally encountered in production knives, anyway, I've never used 1095 at 63HRC or anything), it still sharpens up to a nice, keen edge better than the stainless steels I've tried with similar edge retention (I find it a bit better than AUS8/440C), and it's stainless.
3. VG10, it has edge retention in the upper tier of the stainless steels I've used (CPM154/154CM, ATS-34, that kind of thing) but has a nice fine grain structure that I find sharpens up really well with a bit less effort than similar steels.
