I ranked the lyricists in order (as well as the songs).
On Fire
1. Kuniva (his verse is amazing, the second half was the best part of the mixtape)
2. Fuzz (i know a lot of people hated this verse, but i loved it)
3. Bizarre (funny, shock value as usual. his flow didn't suck)
4. Swifty (good as usual, but doesn't stand out)
I Go Off
1. Bizarre (one of his best flows, i liked the bomb part)
2. Swifty
3. Kuniva
Killzone
1. Swifty (great flow and multis)
2. Kuniva (did great here as well)
3. Bizarre (weak punchlines)
Canon
1. Fuzz
2. Swifty (consistenly good as usual)
3. Kuniva
4. Bizarre (terrible, and that says alot)
Outro (beat didn't work well for 3 of them)
1. Swifty (he kills this one)
2. Fuzz (good verse, but not a great way to close an album)
3. Kuniva (the amount of syllables in his bars were too uneven)
4. Bizarre (dead last place, terrible verse)
