These guys will have their album in every record store in the US and tour the world for the next few years while you sit at home playing Guitar Hero.
Trustkill will at least make there CDs more available to potential listeners. There will be some promotion. And they'll be able to snag some tours cause of them being on Trustkill.
Most bands won't earn money from sales from any label so I don't know why people scrutinize too much on things like this. You might as well go to a label that has a built name, will put your CD out, promote a bit and get you on tour instead of staying unsigned, having your CD available only at shows (online band store + iTunes maybe too) and having no one promote you and no one want to tour with you because they don't think you'll draw anyone
In reality it's a smart move unless you think you're gonna be a band headlining tours, selling out shows, pushing CDs galore and everything almost no band does in this scene
