One difference I know of is the difference in pre/de-emphasis.  The U.S.
standard is 75 microseconds (the U.S. dolby standard, when there was still
dolby-FM, was 25 microseconds), whereas the European standard is 50
microseconds.

Some receivers intended for both U.S. and European markets have switches
which make the actual value used selectable.  I brought a Telefunken 
receiver to the U.S. from Germany which did not have this feature.  The
result is that the sound here is excessively bright in ways that I can't
adequately modfiy with tone controls.  In Germany, this receiver sounded
fabulous.

Incidentally, even when using a properly adjusted high quality U.S.-standard
tuner, I have never received FM broadcasts in this country that matched the
quality of what I was getting from the Bayerische Rundfunk, both on live
transmissions (which were coming from Bayreuth, Salzburg, and various
Munich productions at the Staatsoper and Herkulessaal).  Great clarity,
amazing lack of background noise, and wide dynamic range.
