I don't care about eye candy and never use the external camera so my favourites are GWX3 and NYGM. WAC and LSH take a long time to load, almost 30-minutes for LSH and >20-minutes for WAC compared to less than 5-minutes for GWX3 and less for NYGM.

I currently have careers on the go in all four super-mods and if simulation is your thing try NYGM or GWX but if you prefer spectacle then LSH or WAC might serve you better.

This isn't an one-or-the-other thing and you can have them all if you want.

I used to play with LSH. If your rig is powerfull enough, give it a try. It´s a very goog mod and you get support here - if you wish in german language.
Years ago, there was a small group, playing LSH online via tunngle and skype for communication. That was very nice.

My WAC loading takes about 7 min max. Definitely not 20 minutes. Game loading is pretty short. Just some mission loading and saved career loading take about 7 minute.
