I was bashing the crap out of SH5 upon it's release... allot has changed since those days.
At this rate SH5 is about 6-8 months from decimating SH3. Even with the GW3.0 mod.
One thing SH3 didn't have was the option to build your own mega mod... lets face it, we have a truckload of mods we can mix and match to build our own unique and personalized game. GW3 didn't offer that and the mods just keep on coming. If GR2 files are finally worked out, you are going to see some serious content coming.
