Quality and workflow note
WAV files are usually much larger than MP3 files because they preserve more raw audio information. That makes WAV less convenient for casual storage, but much more comfortable for editing, cleanup, analysis, and intermediate workflows. The actual result still depends on the quality of the source audio inside the MP4.
