Snipe first

Nope, BM will only "beat" MM's at lvl 180~190+, from lvl 130~180 MM will "beat" them. That is, without Onyx Apples.

With Onyx Apples it's different though, BM's will beat MM's above lvl 140~150... (Snipe's damage doesnt get boosted with Onyx Apples). Same goes for ultra-godly BM's, the more powerfull a BM is, the sooner they will "beat" MM's at the same lvl as theirs.

Afterall, I would say they're equal now, because at all levels they're within 10% of each other's damage...

I don't care what the "facts" are. I don't know anyone who uses Apples for every single boss they encounter aside from Zakum and Horntail.

The real fact is most people will never get to 180 so what you are trying to prove is irrelevant. With that said, Marksmen are more powerful on single targets...
