Currently my favorite is the RP Connecticut (the regular, not the vintage 1999). I buy 5-10 packs from CI or CBID and then order again when I run out. I like smoking them on Sunday mornings as the first cigar of the day.
My tastes have changed a ton, i think right now the RP OWR might be the only really smokable RP. I can stand the 1990s and 1992s I guess, and the Sungrown is just short of great. But the rest of them do nothing for me.
