Scuare just holds his style and composure imo that is the coolest way to approach the battle.
SenatorJD raises his voice and almost shouts into the mic fro me that always is a sign of weakness and so does my buddhistic monk kung fu trainer.
Some blow here and there but scuare has more complexity in his rhymes.
It feels more intelligent to me. ( does that win a battle? not really...)
All in all and i am a fan of SJD it goes to square. Just better flow, composure and punches with more depth.
