2.0 has better economy unless you really enjoy scrounging for every last bullet. You find loot items or artefacts to sell instead of cores and the extra ammo options allows you to use cheaper ammo when the best ammo would be overkill. Ammo balance changed a lot in 2.0 though, Tokarev no longer feels like a viable pistol option and 5.45 x 39 is weirdly weak.

Also it's not obvious but headshots do more damage, just like if you hit the core. You can save a lot of ammo that way.
