This question is not for global variables..
So, what should I use in pretty complex function, which may contain at least 10-30 variables?
What I am focusing on is performance. I haven't really worked much with pvars, but they seem simple enough, although I don't like typing too much.

There is no advantage over using Pvars to regular variables, the use more memory in fact. Regular variables may appear to make your game-mode a bit bigger in .amx size but overall performance, I would use regular variables.
