I have not seen a good band with more than 4 people on stage simultaneously.

Any vaguely disco-adjacent band will have more than 4 people on stage because there will be at least keyboards and horns in addition to drums, bass, guitar and vocals. Even a band that simply adds an additional person player percussion to a typical 4 piece exceeds your limit yet can wonderfully enhance the music.
If you haven't seen any of those bands, then that's your loss, but provides no reason to try to generalize about the right size for a live band.
You pick really popular names but in most regular bands when there is more people there is worse link between them...
Glenn Branca Orchestra.

There are good bands like that but not most.
I've seen bigger bands but they suck in comparison.
However your link looks about jazz.
A common rock band is rarely good with more than 4 members because people lose unity and it's just technically harder and people are rarely professionally trained.
