Gmod 'Must have' mods

I just got back into gmod again and wondering if there’s any new must have mods? I remember having space build, PHX, and wiremod. But I can’t remember others.

Vanilla Gmod is fine, but Phx is good to have I guess.

Oh and I remember someone talking about an addon that helped physics, what was it called?

Jinto’s physics mod is what you’re talking about, I can’t remember the name of the ACTUAL mod though.

Wiremod is pretty nice, but confusing at first.
