I owned Metallica pro for a while and played the heck out of it and moved it on. I have not once missed it since I moved it on. The game play became repetitive and to get to the crank it up modes just felt like chopping wood. I like mode based games and GB nails this type of game play. I also like GB the movie so the sounds and call outs really help. The light show is way better on GB and the shots are satisfying(premium). GB’s wizard modes(and mini)are super fun. I’m not really one for art but GB’s art is pretty cool. For some reason GB gets a lot of hate but ever since I got one I just can’t understand why. If you decide to get GB and can’t get into it Metallica will always be easily available. Good luck with your choice.
