We haven't seen Ruby one-on-one against human combatants,(aside from that 1 minute tease between her and Cinder), but I'd reckon she'd be a fierce opponent against Mercury. She is, afterall, a master scythe wielder. Not to mention, she learned from the one of the best of the best: Qrow.

I'm actually a little disappointed because of that fact that we haven't really seen her in her full glory since the Red Trailer.
