Not sure if it's relevant but I enjoy MM's stage persona much better than MP's, I'm not being snobbish but the way MP behaved on stage was far below the integrity of what Dream Theater presents, I would take MP in Metallica and simple love his antiques and fondness for yelling, spiting and demands regarding his ass and balls, but DT transcends that kinda thing IMO.
MM Manginis all over and reacts to the music, gets caught up in the moment and pumped, smiles in ecstasy at the audience and other band members, so he's not stiff or the exact opposite of MP but he fits in more with the likes of JP and JR.
Then again maybe it was better having someone like MP in the band who's so different than JP and JR.
