Ive seen mixed comments on this before,
some say:
Kill Confirmed with Specialist
Search n Destroy
Dropzone
i find kill confirmed with tac insertion ok (respawning on own tags) - but normally results in a load of deaths
what works for you?
from lvl 1 to 20-30 i would say go with infected since u can get the specialist bonus

then from 30 to 80 i play s&d with specialist (gets you 500xp bonus pro perk!) or go on with DZ because you get loads of kills which means you ll get a lot of challenges done...
usually i need 8-10 hours to prestige but if use snipers(for fun) i need 2-3 hours more
