So you live in CO….plenty of places/collectors you should be able to check out all these games for yourself. In a HUO environment you will be able to hear all the call outs/music etc so that’s a non issue.
Since you are looking at music pins ask yourself what music is best for you….if you like Metallica it’s an easy answer…Metallica all day long. It’s a GREAT GAME…doesn’t get old. It can be brutal….have a killer game and then the next game kicks your ass. There is so much going on in this game…also are you looking at a Premium or a Pro…my vote would go to a Premium….it’s got everything you could want. The Pro is good too if it’s all you can find/afford.
AC/DC- if you like their music most then it may be the best choice…..it’s fun. There are some things that will get old…every time you drain the song starts from the beginning….Metallica starts from from a different spot depending on where you progressed so not always at the beginning.
GnR- BEAUTIFUL but gameplay is OK…would get boring quickly. Just not enough there to keep it interesting long term.
Iron Maiden- If you are a BIG IM fan then it may be just right…I have played it and it’s fun but I don’t find the features not as good as what’s in Metallica or AC/DC. I like The music but have just never been a big fan and I am a metal guy.
My opinion is the only one that matters so Metallica it is….JK…YOUR opinion is the only one that means anything…go get some time on these games…reach out to collectors near you if they are not on location and figure out what is best for you.
