If you asked me a few weeks ago, I would say I like the following candidates:
王嘉儀
陳彥庭
何紫慧
but now, I found 王嘉儀 is my ultimate choice because she has a good voice, perfect pitch and she's not afraid of taking risk trying different kind of music styles. She's not pretty but she looks sweet. Afterall, as an artist, the outlook is important unless you are highly talented.
