Well I love my V30s, so nyah! :P
Seriously though, the previous G12T-75s I had in the cab had real problems cutting through the mix and were overly bassy/boomy, possibly exagerated by the fact our second guitarist had G12T-75s in his 2x12 as well, and so things kinda blended together into a bit of a mush. After I switched to V30s I was far happier with my sound, and the overall sound of the band felt bigger as well, which was a great bonus.
Anyway, I prefer a brighter/middier guitar sound than the current metal fad of low and boomy. if I wanted low and boomy I'd switch to playing bass guitar. ;)
