The real GRE is about in line with the practice tests in terms of difficulty (although I would say additional difficulty simply because of the experimental section) - it's much more discouraging because you feel as if every question wrong counts twice as much. Don't underestimate tiredness and sheer instinct in picking choices after a while!
I did find the real GRE to be generally much more forgiving score wise relative to the practice tests. I was dropping much faster in Quantitative after a few practice tests. So that's definitely encouraging because I was anticipating a ten point drop given how unsure I was of many of the questions. But I guess the adapted difficulty does help some people out!
