Comics Valkyrie titles

So I was wondering does anyone have any opinions of the series that are running in the kill time communications imprint Comics Valkyrie: Unbalancex2 (Korean), ??VS, Freezing and I can't think of the other ones right now. My question is do you think any of these titles would be import worthy since I'm currently planning on getting Unbalancex2 & ??VS.

I got a better idea, can you post an english summary/review of these titles.. possibly with a few pictures to see the basic art style.
I honestly haven't heard of ANY of them. >_<

Edit nvm ..
here's Unbalance x Unbalance:
