This really does seem to come down to the sound you get versus the notation you see. Certainly swing (tripletized) 4/4 can sound exactly like 12/8, but the notation can get messy (technically, in 4/4, you need to put a triplet bracket over every group of 3 8th notes, whereas in 12/8 you don't). That aids in readability. Similarly for 6/8<...>

And exactly why old swing songs were written with straight eighth notes but played with a swing feel.
Which is also why I use a separate notation editor when I want to make a chart.
Of course that's me, and we all have different needs and desires.
