Have done GM numerous times and EOTR once. I have to say, I much prefer the former. Overall vibe was preferable. Beer festival in the courtyard is a fantastic extracurricular bit. Size-wise, they’re much of a muchness. GM may be slightly more compact both in terms of stages, etc. and the camping which, if closer to the festival itself, seems more cramped. Far Out is a tent whereas the Garden (I think it’s called?) is outdoor so if you really want to catch something that may be popular in there, get there early. Otherwise fine. Sight-lines much better on the main at GM as it’s a natural amphitheatre, and one of the best festival stages in the world in my personal opinion. You’ll love it. Everybody does!
