No disrespect intended Meth, as Im sure youve had good success with what you describe, but as generic advice in answer to the question I dont think its that appropriate. particularly when we dont know the sound of the voice.
Plus your advice focuses on Waves plugins when Big is using a distressor
When I track I generally go at anywhere between 2:1 and 4:1, fairly fast attack and release (usually with an 1176 - just to give you an idea of the sort of attack and release times im talking about - so with your distressor you'll be looking at similar settings).
At mix, anything from 2:1 to 8:1 depending on the rapper, how much Ive compressed on the way in.
Remember that compression effects are multiplied, not added, so tracking at 3:1 then mixing at 4:1 is like having a 12:1 ratio in a single pass.
Outside of compression, for upfront and personal, stay away from verbs, and maybe just use a very subtle tight delay ?
