It's been discussed like in the previous page if I recall.
Nirvana should win, if in your case it doesn't make sure you have large enough samples and it's not just a coincidence.
For physical BPs, if you're talking about those with no FTP transfer, Nirvana probably wins on those, but those are pretty meh so in the end who cares who wins?
If you're talking about those with FTP transfer, then one of the best options of the augmented Oboro weapon.
Nirvana of course wins here BUT only if you have AM3 up. If you do then the margin is quite clear. Without AM3 Oboro's weapon actually pulls ahead on some BP. When it doesn't, it's quite close but behind.
That's as far as I remember, I apologize if something is wrong!
