I love the Swisstool and especially the Spirit. Both should be great purchase target, if you like quality tools.
I like RangerGrip series too, but usually prefer it more for outdoor use or collection purposes. And personally, I'd like them without the pliers since it might make the whole tool width a little too wide to hold.(I consider my hand size average, usually M to L size glooves for me)
For purchasing SAK, I often find SAKwiki to be a great reference. Usually I would browse the gallery of the desirable length of the tool, find some direction, then research more on the particular models and similar models to find what I like best. Pretty much a Bottom-up approach.
The SAK selector at the Swissarmyknights also does wonder, it is a top-down approach, and if you know what exactly you want, this is the quickest way to find it.
