I'm not counting my wife's bikes(2 going on three).
I have 15 bikes that are built and a 16th I'll be working on soon (Palo Alto frame). There are about three others that are in various build stages that I haven't gotten around to selling yet. Maybe I'll do that this weekend.
Best is a funny word...best to ride? How? Best in the eyes of a c/v forum? I have a few bikes I think are pretty special, but the most special to me is probably the schwinn triplet. I trash picked it with my dad 26 years ago and it's the bike that really got me into cycling. My wife and me ride it all over town and it's a LOT OF FUN; she especially likes the attention and comments.
