anyone try the quick sync handbrake beta?

here i sit, bored, not having an hvec encoder to play around with so i decided to try the qs capable handbrake beta and i'm quite surprised by the results. i've used every qs enabled app: espresso, video mastering works, sorenson squeeze, gom encoder, media coder but i had never tried the handbrake implementation, maybe it's my eyes but these guys seem to get better quality than all the others (sorenson gets the worst, by far, and that holds true of all the included encoders).

i know there's a few guys here that have SB/IB chips and use the integrated gpu's, if you guys could try out the handbrake beta and report if you find the quality likewise surprising, that would be great.
