Teen Gothic

So i’m planning to go to Germany next year (from the UK) to attend a festival but i’m not sure if i should attend M’era Luna or Wave Gotik Treffen. I love a lot of different music and I would like to get to see a bit of Germany whilst i’m there, my fave goth/post punk/gothic bands are Vision Video, Sisters Of Mercy, Bauhaus, Joy Division, Clan Of Xymox, Lebanon Hanover, Rosegarden Funeral Party, Alien Sex Fiend etc. Any help from people who have either attended/know people who have would be super appreciated! 🙂
