Pretty interesting, but I say Nebula has a slighter edge. Mainly because she has better experience since she’s been training under Thanos and been fighting in space for a while now and done more.

I don't know about done more. The Major is prior military and has been a full conversion cyborg far longer than Nebula has been an enhanced one. Motoko is also the more skilled fighter.

So, then, I’ll say her. I don’t know her and haven’t seen her in the anime she’s from, so my knowledge will be below average in this predicament. Sorry. lol 😂
