Just wanted to thank all of you for the replies!
I've been playing SH5 with TWOS for a few weeks now and I think it is growing on me to the point where I give it a slight edge over SH3, even though the ideal, of course, would be to combine the best aspects of both.
While the graphics are an obvious advantage of SH5, I love that feeling when diving to evade a destroyer and being able to walk around the boat, checking on my crew, with that scary yet exciting feeling of being trapped in this iron coffin with them. That key feature accounts for a lot of the "immersion" factor and makes the experience feel more real.
And hats off to the modders for making SH5 a contender!
