Late reaction but oh well...
First of all (now remembers the forum rules).. keep in mind that some artists can also do amazing work "making" things more nasty.
Carnomoloch is a nasty critter on the Daz website and yet our very own Sledgehammer "put it to other uses". Why (re)create a whole new demon when you can just "repurpose" them?
Each to their own but I kinda like that idea: have "them" make awesome critters and then "our team", well, uhm... get's them "other" things to do? 
Now, I'm not gonna lie: if you ask me Deepspace stood out, big time. But... there are alternatives on the site. First, a freebie which I really came to enjoy:

But yeah, our options are limited. But don't cut out the stuff that's on the market short. Not sure if Davo is gonna like this but honestly?

^ I like this. Now, a ton of disclaimers go into effect here because with all due.. nah: with the utmost respect: this figure is dated. Very much dated. I'm not even sure it works with Iray (I made it work btw, so it can be done). Also... it doesn't really look very realistic.
C'mon, the product page alone should be enough to realize the age here. But I'm gonna go on the record: dated or not, I still love this product. No, I don't think it can compete against more modern stuff (like the venus fly traps which, ironically enough, are also quite dated now) but it's still a solid product IMO.
Is there any genre in specific you're interested in OP?
