Out of what you specifically listed: I loved Once, I loved One Man, Two Guvs, heard mostly good things about The Best Man -- but a little less since the new cast.
Once has been on tkts a bit -- but I don't know how often, and One Man Two Guvs is often there.
I also liked Peter and the Starcatchers -- but it's not for everyone.
If we're not having fun, then why are we doing it?
