David Lee Roth vs. Sammy Hagar?

Many will say David, but I disagree. Sammy was an awesome singer. He made four of Van Halen's best albums ever. All multi-platinum. And I believe it was 9 number one hits he got them. They were more sucessful with him. And if David had negotiated with the band and made songs they all liked, we wouldn't have this problem. Sounds like he's a little whiny.
