Actually IMO the best is either the 3f or the 5s depending on your play style. The 5s has two ams spots if you use ams. I dont so I like the 3f because it has the same HP layout but it has a larger torso twist than any of the other variants. 85 degrees vs 60 on all the others so its better for brawling as an srm boat.
I bought the 5m as 5 srm6 and 5 ML sounded good but i didn't realize one spot is a narc pod so you can only feasibly fire SSRM from it. Fine if you are using all streaks.
The 3h might work better for lrm users as it has lrms 20's stock so it has 20 tube launchers rather than 10 like the others.
