Hey CTMAADawson,
Well first of all the Texas is a premium =), did you mean the New York?
You have 3 good choices of lines to grind and they all have different strengths and weaknesses.
USN:
Good AA
Accurate
Decent speed once you get past the Colorado
16 in guns so they can struggle against certain cruisers
Soviet:
Good brawlers
Accurate at shorter range
Tanky when they are bow on, vulnerable sides
AA is not great until you get to the higher tiers
French:
Unique turret layouts
Decently accurate (Republique is definitely accurate)
I would say they are the least tanky of the 3 choices
AA is average
Great flankers and have speed boost
These are just a few highlights of the branches that I can think of right now. When looking at stats remember the Soviet BBs are the new kid on the block while the USN BBs have been on the block for a long time =). Seeing as you are mid-tier in 3 different lines, what has been your experience and which one feels better? It seems like from what you said the French BBs fit you the best so maybe grind that line and see how you like it. The joy of having the lines is they don't go away so you got time to try them all out.
Good luck with your choice and have fun in BBs!
