Well to me it's an easy pick as I grew up with Rush. So sentiments undoubtly play a part when I listen to their music. Imo The Cars gave us some nice hits like 'Heartbeat City', 'Just What I Needed' and 'Drive'. But Rush gave us some (again imo) totally legendary albums like '2112', A Farewell to Kings' and 'Moving Pictures'.
Besides that, I must have visited over 100 concerts in my life. The R30 concert I went to would still absolutely end up in my top 3. What these 3 guys can do on stage is simply amazing. I also think Neil Peart is an alien, no human can be able to drum like that.
So end conclusion: for me Rush vs Cars is like putting Mike Tyson in the ring with Mr Bean....not an honest fight at all.....uuuuuh did I already mention that I like Rush?
