Should I buy SH5 or stick with SH4 for now?

Stick to Sh4 and enjoy its mods.

SH5 graphics are marginally better but they come at the cost of increased hardware requirements. Considering what it's effectively put onscreen I'd say the 3D engine of SH5 is poorly optimized.

The novelty or running back and forth in a 3D environment wears out pretty soon, particulary because there's only one sub modelled. I'm not even sure they modelled correctly the differences between revision A-B-C. They look all the same to me (except the missing stern tube in type VIIA).

It's really just some eyecandy thrown with no real purpose. You cannot turn the various knobs and handles by yourself. Most dials are static.

The crew is composed of puppets staying in the same spot all the time and repeating the same animations over and over.

The interface is a huge step back from SH4 and SH3.

Crew management is a joke

The bugs in this software are as numerous as ants feasting over a decoposing carrion.

Last, there's the wonderful DRM scheme which is entirely dependant on staying connected to a remote server all the time.
