Which Mega mods are best and why

[Sledgehammer427]

well...I don't know about 4 or 5 but I can think of 3 offhand.
Trigger Maru Overhauled(TMO)
Real Fleet Boat(RFB)
and the Game Fixes Only mod(GFO)

now, it really depends on what you are looking for, there is no "better or worse" case here, it just depends on what you want from the game.

TMO has by far the most challenging AI, the destroyers can basically see underwater and hunt you down mercilessly. If I'm not mistaken, and don't go around saying I said this in case I might be wrong, but TMO's destroyer AI act like allied AI against the U-boats. it may not be horribly realistic, but it's for those looking for a challenge

RFB, as implied, is probably he most realistic. LukeFF and team went a very long way to ensure you get the most realistic experience possible, I use this mod so I can tell you a bit more about it. deck gun loading times are longer, and no longer will enemy ships explode in fantastic fireballs, you have to actually sink them the old fashioned way. I once spent 12 hours game time hounding a merchant because 2 out of 4 torpedoes didn't explode, and it wasn't sinking very quickly. I ended up chasing it until It stopped, then gave it another pair of torpedoes coup-de-grace. The aggravation you feel is the same aggravation a fleet boat captain would have felt and thus, I prefer RFB's take on the Pacific war.

now I haven't looked into GFO, I always counted on patches and supermods to take care of the bugs and shortcomings but my educated guess is if you prefer the stock campaign, stock boat behavior, stock crew behavior and are looking for an entertaining gaming experience and not for ultimate challenges and realism, GFO would be your pick.

OH, you can count in RSRDC and Operation Monsun. almost forgot
Run Silent Run Deep Campaign is a total rewrite of sh4's campaign layers, Lurker did a lot of research into how the battles were fought and was probably tired of running across task forces with 3 Yamato battleships (the japanese only built 2 and the third was converted into a carrier) and unrealistic convoys so he went through and put things in order, realistic task forces and convoys, both of which sail from their respective bases and ports on or around the time they did in real life. Lurker also added in patrol orders that match the campaign, you won't be getting the same patrol orders through all 4 years of the war. it's a must have if you prefer realism
(which I do, so I run RFB+RSRDC)
Operation Monsun is another mod made by Lurker that follows the U-boat campaign from 1939-1945. it has been just as well researched as RSRDC and it is not only the only full U-boat mod for SH4 but also, one of the best.

hope I could be of help
