Sailor Steve said true - it's personal taste which mods to use, everyone has own list, but there are mods described as "must have". For me must have are GWX 3 Gold, SH3Commander and hsie's hardcore exe fixes as a base. After many tests and being based on my own experiences I can propose You to use mods from my jsgme list:

AChSoundMod_v1.2
Conus' Historically Accurate U-boat Emblems v1.3
GWM - No Torpedo Icons
GWX - No Medals on Crew
GWX - Open Hatch Mod
OLC's Modified Searchlight Beams for GWX3
SH4StyleFlags_GWX
Sub Image mod
TheDarkWraith_Ship_Plane_Fire_Damage_v1_4_SH3
Torpedo damage Final ver2.0
Transparent Console
WAC4.1 SubPen_animated_18.02.2010
Waterstream+Exhaust Combi V2.3 for GWX3
Waterstream+Exhaust Combi - Single Exhaust for TypeII
Wooden_Lifeboats_Mod_1.1
Rbs1_SH4_Effects_GWX_30_71
Rbs10-enhancedoilexplosion
Merchant_Fleet_Mod_3.2
M.E.P v3
M.E.P v3-Patch
FSF for M.E.P v3-Patch
M.E.Pv3 VisualSensors-GWX3
GWX - Captain America's Officer Icons
TMT v2
hsGUI v3.1 for GWX or ACM GUI Reloaded hsie's Edition v1.15
Red Night Map

This mod soup is stable, good looking and gives me realistic impressions.
