I agree that the Van Hagar lineup was the best. Perhaps my decision is biased by the era in which I was raised and I'm not discounting some of the great Roth songs. I just think Roth was/is a bit of a clown, which was evident by his egotistical goofiness during the MTV music awards of '96. I truely believe that they were considering taking him back until he started jacking around at the show. After that, it was out the door for Dave.
As for Cherone, he lacked the luster of the other two frontmen, and Van Halen III was the proof.
