Quentin ftw! (unfortunately )
Emma may be far superior in skill and finesse, but that can only compensate for so much raw power. Quentin as an omega level teep is simply too strong and he already defeated her during "Phoenix: Endsong".
If she'd go all out, perhaps she could give him a good fight, but she would still loose in the end.

It's hard to say really.
Quentin when he was a student was far more intelligent than her, but she was actually strong when it came to telepathy. After his kick abuse, Quentin should've won.
Stepford Cuckoos needed to pull Kick + Cerebra to take him out.
