The only thing that PA does that is kinda nice is its per application volume control. Thats it. But its soooo huge that it simply isnt worth it to get that slight advantage. It's performance is so bad that even the slightest cpu load makes it skip and crackle. Simply put, it's some of the worst software ever written for little to no gain with lots and lots to lose.
