Having made some more research into it...
Meantone temperament came first. This one is made to sound good in C major and a few other keys. It will sound a tiny bit out of tune in most keys TLDR: A few scales are exactly in tune while most are out of tune.
Well temperament came second. Not quite as in tune in C major as meantone but this can be used in more keys than meantone without sounding out of tune. TLDR: A handful of scales are extremely near to exact tune while some are slightly out of tune.
Equal tempered is what we use nowadays. All keys sound the same, never quite in tune but never too far from it either. TLDR: Everything is close to being in tune but nothing is exactly in tune.
Now of course a note will always be in tune as there is no law of physics that says an A must be 442 hz instead of, say, 440 hz etc. so everything above applies only to scales and the chords in them.
Also, I don't claim to be an expert with this stuff so there might be mistakes here. Even so I am quite certain that the talk about "tone" and "character" of notes (Keys to be exact, not individual notes) is the result of meantone temperament and well temperament tunings being used before the invention of the modern equal temperament tuning.
