Well, Yulaw is a bona fide bullet-timer whose top strength "feat" would be when he stopped 2 speeding police motorcycles with each hand while his arms outstretched (v-fly style; which means he was using pure strength with very little leverage) dead in their tracks.
Each bike (I'm assuming) when moving at around 30mph would generate about 4800 kg-m/s momentum.
His durability is in question, tho as he was still trying to dodge bullets.
Oooooo. Damn. I don't know...This is a good one I think. Selenes healing factor will help. I have been voting Selene most matches because of her speed advantage over them.
I am still going to vote Selene6 /10 because she has more experience fighting superhumans, Yu Law really just assasinates versions of himself and I dont feel like that stacks up to hundreds of years fighting lycans and vamps.
That motorcycle feat is a damn good one though.
I think it comes down to Yulaw having so-so durability vs Selene's crazy soak going against Yulaw's ridic speed bullet timer "feats" vs Selene's questionable super speed (although she certainly has superspeed, it might well be below Yulaw's unless she has bullet-timer "feats" in her belt w/c I can't recall her having).
Strength might be on Yulaw's side, tho. Although I'm sure someone who is better versed with Selene's strength "feats". Strength is not so relevant as it should be, however. As Yulaw's seemingly mortal-ish soak would easily be bypassed by Selene's lethal strikes.
My respect thread for Yulaw. And in my humble (hehe) opinion, arguably the best thread in the movie respect forum
