I would personally go with Jacksons camp because he has a large amount of good fighters that can spar with one another and mimic a specific opponents techniques(when GSP was getting ready to fight BJ he trained with Rashad because he has very quick hands like Bj and a while back i seen an interview where Marquardt said that having GSP train him on how to set up clinches and takedowns with fakes have really improved his ability to complete more of his takedowns).
Plus you've got Greg Jackson in your corner and hes proven to make good gameplans for his fighters i.e. when GSP fought Bj,he and GSP came up with the idea of keeping BJ pressed against the cage in order to keep pressure on his shoulders so that they would get fatigued,fill up with blood and lactic acid and therefore his boxing wouldnt be as effective as it was in the first round of their first fight
Dont get me wrong Team Blackhouse are a close second,the only reason i put Jacksons camp first was the fact that they have a wide range of fighters in different weight classes and of course Jackson himself
Its like a black blanket coming to life
