The audio track is the same in WAV and AIFF, so no there is no difference. The only difference is the “container” that holds the metadata (song, track name,…) that has slight differences, but all you need is there.
The main difference:
WAV -> invented by Microsoft to compete against AIFF as they saw it makes sense to have something lossless.
AIFF -> was there first, Invented by Apple in 1988 and the mother of lossless file formats
AIFF has a slight better play latency on older Macs, as playing AIFF files is hardcoded into the operating system (CoreAudio). With every Mac since 2005 the problem no longer exists as also WAV has been integrated into CoreAudio.
WAV has advantages on Windows XP Systems, as AIFF was deliberately hindered by Microsoft and could not be played by the Windows Audio Service. With Windows 7 and up you should have no problems.
