Hey AWK-H, welcome to BF! And welcome to Spydieland!!
Now I'm going to really surprise you and bust your preconception:
Definitely, get the SERE 2000!
You see, I've never held one, let alone used one, and I don't particularly like linerlocks, but the SERE is the way to go.
How do I know? Because I own around 20 Spydercos (haven't counted them recently, and three more are on their way). That's why!! And oh yeah, I DID handle an original SERE Attack huge-butt lockback when they first came out in the, uh, early eighties?? Dayam, that was SOME hunk of knife!
Now that I've biased the results, let's hear from the rest of the gang who will give you a much better answer...

PS I honestly don't know--I handled a Military ONCE, and that was years ago...
