Reminds me of an argument I had one time about James Bond. Just got done with one of the latest Bond movies and was making a case for Craig being the best Bond and he kept swearing Connery was the best. At the end of the conversation he admitted he hadn't seen any of the Craig Bond movies...
I am a fan of all 3 of the bands, DL and both versions of VH. I tend to lean towards Hagar as he has a better voice and is hands down a better musician. Yeah Dave is probably one of the best "front men", but I'm not going to see shows anymore. I'm just listening to the music and not seeing the crazy parties and antics anymore and that's why I give the edge to Sammy. Both have great songs, but if you take out the covers and instrumentals, VH put out more music with Hagar and much more refined. I love the Dave 3 and a half minute songs as much as anybody in here, but if I choose to put on a VH album it's always 5150 or the last 2 Sammy records. OU812 had a few moments but it doesn't get much play anymore.
For Def Leppard, hell my favorite album, and it's not even close is Slang. Other than the title track, not many DL fans can name more than one song on that album. If you're scratching your head right now, go give it a listen. I don't think you'll be disappointed.
If I had to choose, I'm done with music pins and sign me up for Rick and Morty!
