Voice quality is pretty much always the same on gsm networks.. I did not find any metrics on the subject.

Depends on the codecs that are used, and the bands available. Some devices might not have more recent codecs, and therefore might sound worse.

Other devices might have newer "HD voice" codecs available, and could sound totally different.
