Yes, we use QWERTZ in Germany, but it's muuuch closer to QWERTY than France's AZERTY (needs shift for numbers!). The difference between QWERT{Y,Z} is those two keys (Y and Z are swapped), the shape of the enter key (necessitated by an additional key), and basically all of the special keys. Many of those moves are due to ä/ö/ü/ß. Meanwhile, AZERTY is very different, and even typing alphanumerical things requires paying serious attention to key placement if not used to it.
Having lived in France I'd say switching from the French keyboard to most other western layouts is especially brutal (or making the switch in the other direction). Took me a good while to readjust to the numbers being on shift and the special characters being the default. Very brutal for passwords :D
