Grading aside, depending on which country you pick, holidays, hours and all the comp related bits and pieces could be a nice improvement, assuming works councils support your 'arrival'.
I probably will head to France, it's the only foreign language that I learned (other than Latin, in which I got a better grade than I got for French), and therefore is my best chance of getting up to a respectable level in the shortest amount of time.
The challenge may be that I'd not want to be in Paris.
The way they have done this historically is to look at the pay scale for your role/level in the country you are going to. If you go to the US this is a big bonus, as they pay more - I don't know what my level would earn in yoorop, but there's one way to find out.
