This is for me as clear cut as it gets. On the one hand you have Warrant an average band, which when they first came out released some quite good music but faded into oblivion really after their first sucess. I'm not going to cut them short because there first 2 albums weren't actualy that bad, but nothing really stands out for me as great music. I quite liked the song Cherry Pie but it's almost laughable for me to compare it to even some of the lesser known songs from one of the greatest Rock bands of all time.
And that brings me nicely onto Guns n Roses. Not only are they probably the most popular rock band of all time, there music has stood the test of time. If I go nowand listen to the Rolling Stones, or Led Zepplin, I can aprechiate what great music it is, however it just isn't popular nowadays whatever people may say. GNR's music still sounds good today, thats why there my pick to win the entire tournament. They have every one of the criteria required to be known as great- music, lyrics, huge main-stream popularity, influence, mark on the music industry, not to mention possibly the greatest album ever produced in my opinion in Appetite For destruction. Guns n Roses take it easily in the end.
