SB if ur new or so so at playing sneaks for the first time cuz that 2hander PA demolishes a lot. And personlly better at low rr than the other 2. Inf at middle RRs and quiet nice if your temped out. I can't comment to much on NSs cuz they highest i ever made was 24 but from personal experiance I have more trouble with INFs than NSes at middle-higher ranks. Never had trouble killing nightshades unless they were really high rrs cuz personally they are squishy as shit after they pop all their toys and ur still standing
