What is the best European pride?

I am planning on going on a Europe trip this summer for 7 weeks. I am going alone which is scary but exciting at the same time. I am currently planning the order that I will be visiting each city. While I am there, I want to visit a European pride. I was wondering what the best one to go to would be so that I can plan to be in the city for the date.The cities that I am going to are:DublinLondonParisAmsterdamBerlinRomeBarcelonaAthensMykonos
