I would say Bpom Ruk. In both lakorns, both ladies lead the entire storyline so it's important that both ladies are up to par with their acting and both ladies have done an exceptionally great performance but Pueng's speech bothers the living day out of me while Kwan, this has to be one of her best acting gigs so far. If it wasn't for Kwan, Bpom Ruk would be quite dry.
Oh yeah, one of the reasons why I choose Bpom Ruk over Ngao Asoke is Pong's stupidity, he's blind till the very end. -_-
At least Win already protected and confessed his love for Kwan half way.
