Channel locks are my favorite. If you want a pliers that will grip most anything try this one. It grips as good and similarly to a pipe wrench but is more versatile. It won't get into all places but is one of the best tools out there for getting rounded off nuts off. It will grip any bolt even without any head on it. It is almost indestructable to. I've had a cheater pipe on mine for tough stuff and it's still like new. It doesn't require you to squeeze to grip, it pulls tight by itself. Once it's on the nut you can push with an open palm and it won't slip.
