What is difference between using SetPVarInt and variable[MAX_PLAYERS]? What is better and which one should I use?

"PVars are several times slower than regular variables. It is generally more favorable to trade in memory for speed, rather than the other way round."

That has all been explained multiple times, please search a little. Calling a function is slower than accessing a variable. Only use PVars for cross script sharing or in cases where an array would be overkill (for example passing a value to the next dialog).
