I'm not familiar with that helmet at all. You can try doing a search for comparison threads. Hopefully someone will chime in that knows. As for the BKBT, I'm a medium build 5'7" and it fit good, maybe a very slight tad on the large side, but only for picky eyes!
This is a helmet by Marrow Sun, here are a few posts that have it in there:

I'm 5'7" too. If it looks good on you then it looks good on me!
