Been playing around with various scoring systems I've devised and this is what I've settled on as the best mercs in the game.
There is no ranking within the four tiers.
The 'Price' column refers to the price class of the merc, 1 is the highest.
I eliminated mercs with the 'old dog' trait from consideration (these mercs do not increase their skills / attributes, like Len in JA2), as well as any mercs with wisdom or agility below 70. Other mercs were eliminated for having cumulative attribute scores that were below a certain threshold using a weighted scoring method I created.
The 'primary' and 'secondary' roles I devised are somewhat of my own creation... 'gunner' refers to the auto weapons perk, 'heavy' refers to the heavy weapons perk, 'scout' could refer to a number of different 'silent takedown' related perks such as H2H / martial arts, ambidextrous (dual silent weapons), stealth, etc. You have to have the stealth perk for scout to be a 'primary' role though. Stats above 70 in explosive, leadership, medical, and mechanical qualify as 'primary' for their associated role, and stats between 40 and 69 qualify as 'secondary' for their associated role.
The likes / dislikes are taken from JA2. From what we've seen so far they track with JA3, but there may be surprises - most of these haven't been verified. I only added like/dislike info for mercs that are on this list, so it's incomplete by design.
Kinda bummed that none of the new mercs made the cut, but oh well.
Also in case anyone hasn't seen it yet, the data for this comes from @DougS2K's spreadsheet:

Anyway, I hope someone finds this interesting. Feel free to have your own opinion, this is just mine. 🙂
