After tossing the proverbial coin, I'm going to say the Huntsman.
1) I already have one.
2) I have a bicycle multi-tool that has a Number 2 Phillips, so the one on the Fieldmaster would be redundant.
I wouldn't complain if they removed the small blade on the Huntsman and moved the punch/awl to that location.
I find the punch/awl much more useful when it isn't centered on the bottom, when removing thorns from my bicycle tires.
The punch/awl position on the Recruit is much, much better.
If I had the funds, or it was going to be issued to me, I guess the Pioneer X would be acceptable. No back tools, the punch/awl is in the right location, and it has them super handy for eliminating those ultra annoying loose threads, hangnails, and wild hairs scissors.
