VH have never repeated themselves, even II had a much different sound than the debut, so I dont expect them to start now. I never base "better" on album sales, it's purely what MY ears like. That's why I will always like WACF better than the debut, regardless of how many more records VHI has sold.
A possible benefit a new album could have, is maybe the band will actually attempt to promote it. I'm still amazed and disappointed that Al didnt do a Modern Drummer cover story for ADKOT.
