I own both SH3 and SH4. I play SH4 with TMO to experience the American side of the war, I have only briefly dabbled with the U-Boat side of things.

SH4 does several things better than SH3, firstly the graphics are much more detailed and the look of the water is indeed lovely. It also does a few minor things better aswell, like a much improved crew management system.

However it is still just as buggy and unstable as SH3 (atleast for me) which I think is a shame.

However, I still prefer playing SH3 with GWX and and a long list of mods. For some reason I have a lot more fun sinking ships in SH3. This is probably just down to the talent of the modders and the fact that SH3 has been practically modded to death so you once you realise what you want out of it, you can tailor your experience to almost exactly suit your own tastes.

I'd say get both, Silent Hunter 3 is very cheap now.
