As of now I play SS6.1 with SSTC + Y&Y + Crimson Tide + RAJ +XBAI + LCAI without RR/BGR.

I'm very happy with it since it feels like Vanilla with SS system & AI, effectively retaining the vanilla "feel".

Then I just heard about Zuma mod. I'm feeling like starting a new camapgin and if I did I'd like to start one with a new mod. How is Zuma different from my current setup?
