I like Gerber's 600 series. They aren't quite as shiny as the others, but they're built incredibly strong. The snap action pliars act more like REAL pliars than the fan handle style ala leatherman,victorinox etc. Once they're open it doesn't matter which way you twist, pull or pry with them the handles don't fold. The blades don't hold the best edge, but all the screwdrivers and everything have served me well and haven't become rounded over at all after a few years use. The tools are all on the inside of the handles, so you don't get pinched when you have to put a death grip on something too

I wore the sheath out on mine and ended up making a new one out of kydex. The first try worked but wasn't as nice as I would have liked and I suddenly had a who cares if it(the pliars) gets broken attitude. Figured it was old and I'd just get a new one. So I REALLY beat the hell out of it. I used it to work on woven wire fencing, and as a crow bar and hammer and all sorts of things. It didn't break and I ended up making a better sheath, still beating on it
As for your original choices.... of those I would pick the supertool if you plan on seriously using it. The swisstool jaws aren't as big as the competition and the tools in the handle seemed to be borrowed from an SAK, they could be built more solid. Not a bad tool, but far from my first choice.
The wave is nifty, but I have reservations about how sturdy the blades are that are simply held on with a torx screw, and overall its not as solid as other tools. A little on the small side too.
I haven't handled a suptertool much to give much of an opinion on it, But from what I've seen its the closest thing leatherman has to a full size, sturdy set of pliars.
