I love the frigates! I like all of the cannons that they offer. It's so much easier with a small crew to run from one cannon to the next to be able to get off shots. It will also hold more crew members, if you want to get a large crew going and still carry a nice cargo.
The war galleon is nice if all you want is to load up on gold, which does come in handy when trying to recruit a crew. The problem is there are a lot of glitches with the war galleon that can be frustrating. My friends and I started calling them 'water bugs'. You'd be shooting one of the cannons on the main deck, then let go to switch sides, and end up floating over the water.
This can be fun when you WANT to do it, but not when your ship is under attack. You can't get back on deck without tping or pushing through a weak spot, either. And then you'll have to do it all over again. It makes for a fun glitch every once in a while, because you fly along beside the ship, but......
As far as the specifics of each ship, it may be easier for you to actually go on the game to the shipwright and click on the different ones to compare them. It will bring up the specs for all of them, and you won't automatically buy them. You have to actually click on 'Buy'.
