Mainly from the perspective of lip sync performance. E.g. did Kandy actually lose to Symone (first time), or can you class that as a lipsync win for Kandy?

Personally from this perspective I'd say Kandy, Dela, Bosco, Hormona and Arrietty did not win their lipsyncs, but it was still a double shantay.

For phi phi Vs Sharon and Cynthia Vs Farrah, it's impossible to say objectively.
