Future V1 - Flow pauses too much. Google diss is weak. Lots of filler and weak rhyme scheme.
Senator V1 - Late verse diss, Soundcloud line is very nice, name diss with the other artists is nice as hell. Who the fuck is he flip is okay. Flow is incredibly strange, sometimes on beat, sometimes way off. It sounds decent but unnatural at the same time.
Future V2 - Doubletime is lame, you should only rap faster if you have more to say, so if you're going to write filler, don't. Soundcloud shout-out is a nice flip.
Senator V2 - Street flip is hilarious, especially with the acronyms. "Fuck your girl" bars are mediocre. Enunciate! is strong, fast flow and gun flip are good too, 'fake' finisher is strong, actual finisher fails at being funny.
Senator wins with more relevant disses.
