I would always buy a Leatherman Charge TTI instead of a wave. They are more or less the same, but the s30v steel is much better then steel in the wave. The only reason ton buy a wave is the fact that it's a little cheaper.
Personally I think the Victorinox Swiss tool Spirit Plus is a better multitool than any leatherman. However I carry a leatherman charge as edc, because the accessibility of the knife is much better (and that's the option I used the most). But if you back the multitool up with a knife/folder I think the Swisstool spirit plus beats the Leatherman.
But it doesn't matter much, you can't go wrong with a Leatherman either.
