Yep!
While I like SH4, SH3 will always be on my computer. I just prefer SH3 over SH4. I play 'em both as the mood suits. And SHCommander is really icing on the cake compared to the lack of something similar in SH4.
As far as super-mods go, I can't really say. I doubt you can go wrong with any of the super-mods.
I've only played GWX. One day I hope to try NYGM and the other super-mods but I have a feeling that day may be a long while coming.
Also, with what hsie and stiebler have done with their patch kit, SH3 has been taken to a whole different level- can you say "Wolfpacks!"?
