I have both and I have placed them right next to each other side by side. For me Metallica still blows GOTG out of the water. I think the big difference for me is the Grave marker with stand-ups, it makes it more enjoyable when you have to get in the channel and knock them down to progress further. I also like Sparky way more, it seems more interactive and is really risk v.s. reward-hitting Groot is just not the same for me. Finally the metal ramps just seem smooth as butter. GOTG is a good game but Metallica is a great game!
