Wow fantastic photos! As I'm anticipating their show in LA, I think I come in with similar thoughts to yours. I feel like I have to see Coldplay live because that is where they are in their element. The difference between Coldplay and U2 for me is that I would probably see Coldplay once per tour when they came around, but if U2 stops by for multiple shows I would buy tickets for every night without a second thought (which is kinda what I did when they played 5 shows in LA...)
