MOV vs MP4
MOV is what Apple devices record; MP4 is what everything plays. They are close relatives — MP4 was derived from MOV — so converting between them is usually just a change of wrapper rather than a re-encode.

What MOV actually is
MOV and MP4 are structurally almost the same format, which is why converting between them is usually a matter of relabelling rather than re-encoding. MOV allows Apple-specific codecs such as ProRes and Animation that MP4 does not, which is why editing workflows stay in it.
A MOV recorded on an iPhone is usually H.264 or HEVC and plays anywhere. A MOV exported from an editor may be ProRes, ten times larger, and rejected by the same places.
What MP4 actually is
MP4 is a container: it holds a video stream, usually H.264, an audio stream, usually AAC, and any subtitles or chapter data, and describes how they line up. Almost every device made in the last fifteen years plays that combination in hardware, which is why MP4 became the default.
Two MP4 files can behave completely differently depending on the codecs inside. A file that will not play is usually an unusual codec in an ordinary container, not a broken file.

Questions
Is MOV better quality than MP4?
Neither is a quality. Both are containers, and the quality is whatever codec is inside. A MOV and an MP4 holding the same H.264 stream are visually identical.
Why is converting MOV to MP4 so fast?
Because the video inside usually needs no change at all — it is copied straight across into the new container. Only the packaging is rewritten.
