Actually I've noticed quite the opposite. At least in the more populated parts of Europe, in my experience Apple Maps does fine and in some cases does better than Google Maps (in my home city of Berlin I find Apple Maps to have been an improvement, primarily in the department of Apple Maps "knowing what it doesn't know" where as Google seems to guess and be wrong. Also, transit. Google is terrible for transit in Europe).
I recently used Apple Maps to roadtrip through Germany and Austria, and it worked without a single hiccup. This summer I had the beta running in Switzerland and it was fine.
In the darker corners of Europe, well, I'll just say in Belgrade iOS maps literally had nothing but a pin. No streets at all. So it seems wildly dependent on where you are.
