Depends on what you like. There is,

GFO, Game Fixes Only Mod,

TMO, Trigger Maru Overhauled,

RFB, Real Fleetboat,

FOTRS, Fall Of The Rising Sun.

If you have a huge hard drive with lots of room, get SH4 Multi Install, and load all of them up, and pick what you like the best.

Each megamod has an appeal for each person. So far personally, I go between TMO, and FOTRS. FOTRS has a lot of improvements like more American, and Japanese planes for variety from the stock version. So you might see Hellcats, TBFs, Corsairs, and others.

TMO was my first megamod, and it is the most flexible to me for balancing between entertainment, and challenge, for my limited time for playing the game, and sometimes long interludes between playing it.

But pick your own favorite. It's the best advice one can offer.
