Get the Tamiya 1:350 scale Round-bridge Fletcher as an introduction to ship modeling in this scale. The parts go together well, the instructions are good, there are a lot of different camouflage possibilities, and there are some excellent aftermarket PE sets available. There are some problems with the kit's guns, but don't sweat them on this learner kit.
The new Trump 1:350 scale Square-bridge Fletcher has a number of problems with it and I would not recommend it as a learner kit.
I generally do not recommend a 1:700 scale kit as a learner kit. The detail kit parts are small as is the aftermarket PE. I have found that it is easier to learn the processes large and then go small if that is your ultimate goal. (Thats how I did it when I tied fishing flies).
Use the Fletcher as a learner kit. Pick up the tricks of photoetch application. See how you like the whole ship modeling genre'. If you are then comfortable you can transfer your knowledge to the big (i.e. more expensive) battleship kit.
