US games > EU games.. Let me explain you why!
US has a bigger, more active and constan twink population than EU, making majority of players better and more experienced and understanding towards the meta of 19s
EU has great players, just not enough to provide quality games as often (or games as a whole) as US.
While pretty much all Americans speak English they have it easier to understand the game whereas to alot of EU players, English is a second language and believe it or not, but that is also a factor that plays a part to become a better player: understanding the fucking game
Just my 2 ce... no fuck that.
