Punches: AK, better punches, only Z's very last line was halfway decent, so AK takes this category.
Wordplay: Neither, neither had any real wordplay
Multis:Neither, both used 1 syllable rhymes
Personals: Neither, also no personals
Opener: AK, Z had an ultra whack opener
Closer: Z, better than Ak's, your last line was filler.

Most of your verse was metas, except of your finisher that was a filler. Bad. Go out with a bang. Z's verse was all filler, except for finisher. So that's no good. No filler at all. Add some wordplay and multis for complexity, connects punches.
