Moving to US servers is the best decision I've made in Overwatch yet (I'm a UK player). 100 ping is worth the trade off of having less toxicity and more communication.
Joined a group the other day while solo Qing and this one guy turned on his mic and started going through greetings in different languages it was fairly amusing until no one replied at all
I like all servers, when it is early and I want to play comp, Asian servers to avoid quitting hours. I want to say the eu and us is about the same. Personally, I just like eu for occasional UK accent.
