I have two of the three, and the one that I am missing- the Squirt- I have a similar model.
Quite honestly, out of the three, I'd suggest the SOG CrossGrip. It is the largest, but not by much, and the pliers are significant. The others have pliers that are good but not up to any heavy duty activities. The CrossGrip's pliers aren't up to anything too major either, but seem significantly sturdier than the others. Plus, the compound leverage actually does make a difference on such a small tool.
