Hi, Josh, and welcome. You want a knife that you can use.
I've had lots of PM2's in various steels and they're all good. The ones in the expensive super-steels may last longer between sharpenings, but they can be much more difficult to sharpen. And...for normal EDC, most folks don't use a knife enough to dull the blade very often at all.
So, I reco the PM2 in a plain S30V blade for a bit over $100. Will last you a long time for casual EDC.
The other two knives are good knives, excellent, but VERY heavy-duty and will be a brick in your pocket. They are very good to have if you need that much "fire-power" but totally unnecessary for most of us who are just fine with PM2's, Caly3's, Sage models, Native models and Chaparrals. Leaves a lot more room in your pocket...and in your wallet.
