That's the thing, man.
There isn't supposed to be a best gun. You chose guns based on preference.
Under no circumstance should a gun be determined as "the best" by the general public.

You pay the extra money on the BAR to give yourself an advantage.
Your purchase is not to achieve victory without putting in the effort to learn to fight.
If you want victory, stop hiding behind your wallet and learn to play.
