Is NIN better job than MNK?

[Butcherboy]

I was on full i120 and a couple i130 augmented where-as he was on majority i120 and a couple i130 Dread gear and i130 Magitek MNK weps so I'm assuming he is some-what skilled and this is throughtout World of Darkness on all bosses, I don't think it could get much fairer than that really, and we were mostly neck and neck sometimes around +/-20 difference to eachother but apart from that not much in it.

Having better gear does not equal good at a job
