The annoyance factor also depends on what airport you're talking about. At FRA, there are often much longer waits for the Non-EU line. But in Stuttgart, there are 2 EU lines and 1 non-EU line, although there are usually >90% EU citizens on any given flight. So I often breeze through Immigration at STR while 100 EU citizens stand in line.
One time clearing departure passport control at MUC T2, I (US citizen) was directed to us the EU National line by the folks herding us to the lines. Got through w/o a problem.
