I'm for whatever makes the chart easier to sightread
+1
I'm (albeit slowly) reaching this position.
Nobody listens to a song for enjoyment and asks "Does his chord spelling tables meet my approval?"
Or says "If this guy doesn't know how to read sheet music I'm not gonna like his songs."
That said, correct music notation is very important (even crucial) in some contexts but it isn't the end all and be all.
Just my 2 cents.
