Finally decided on boost 3, I really wanted to like boost 0 and 1 as they definitely feel more snappy and PC like but in the end I was getting the most kills with boost 3.
Boost 3 is definitely the most sticky and might feel like sludge to some. Unfortunately, it's what I'm familiar with, second choice would be boost 1 and newer players might like that best.
