As stated, depends on your style. If you're a rushing type, you're not gonna think the LSAT is the best.
I actually think for Best sniper the guy above put them backwards. XPR if your aim isn't the greatest, as you'll likely be to get off a couple shots in a row, where the DSR takes a bit to handle if your first shot misses.
I could see that - but I honestly found it to be the other way around. Then again, I rarely miss completely. With the DSR you can sort of lazily line up a torso shot and land a kill pretty much every time.
But if you're a good enough aim with the XPR to OHK every time, you can clear out four rushers from forty feet away before they even know where you're camping.
At that rate why not use the SVU? Better fire rate, less recoil, OHK to the head every time lol
