Yeah the Mesa still sounds GOOD for rock, but it's not the cabinet I would buy if I were in a poprockpunkclassic band. The Orange wouldn't be my first choice either... I would choose the Orange cab if I wanted stoner rock or sludge sound a-la Sleep or High on Fire, something with gummy sticky mids. The Marshall 1960 with T75's pretty much laid most of the genre and is still heavily used to this day, but a 1960 with Chinese G12M speakers would be that much better. For 1960 with G12M speakers, think Hendrix tone. The Marshall 1960 is the cab that you want, not the Mesa or Orange line.
