I have that pliers set, the PL307ACF... I also have this set, the PLR300G, but they don't see as much use as that single pair of 47ACP's.

As for the tongue & groove pliers, I have a 12" and 10" made in the USA from Tekton. They do not have cross hatched teeth, but they work just fine. I have had them for a few years now.

You can also buy a set or pair of Channellocks, they are USA made and easy to source from local and online vendors... I have not invested in Snap On because they don't see daily use. I also need to pick up some Snap On long reach pliers & cutters while we're on the subject, I'm still using Tekton for those too. But again, non-daily use items.
As for Vampliers, those are awesome. I don't have a pair, but I have used them in the past (borrowing them from co-workers). I don't know if they will work any better for hose clamps though, because the grooves are meant to grip the head of a damaged screw/bolt, not a hose clamp.
I actually want to buy a pair of these (but have not gotten around to it yet) for proper purpose built hose clamp pliers, made by AST...

Matco also sells them (so does Snap On);
