Onetap is definitely 10x more optimized than Neverlose. Not only is Neverlose just Nemesis, but Neverlose is overloaded with a bunch of useless shit.
The Only other Cheat I'd say you'd get the better Optimization with, is skeet.
> However, Skeets' been around almost since the Game was released, so it's had time to be optimized and run well.
