I use mostly the built-in ones.
Oh, that and ones that I programmed myself. I recommend teaching yourself Jesusonic and making your own awesome plugins!
The js limiters are good, but if I want to use a cockos plug for limiting I use reacomp with limit check-box ticked. (not if It could only have a limit level threshold It'd be fantastic)
Did you mean "limiting", or "limited"? Do you want plugins that are limiters, or do you just want a broader collection of plugs?
The only ones I use that are not JS or Cockos are Stillwell. To answer both questions, Event Horizon is a good limiter, and there is a JS version in Reaper. The only other plugins I use regularly are VibeEQ and Rocket Compressor. Those three add some character, and the Cockos stuff covers the transparent side, so I think that covers it pretty well.
