Very ripe
The first two are inedible as far as I'm concerned, they're very unsweet and not even as healthy
The middle is acceptable but still not the best, as it's starting to get sweeter but not fully there yet
Very ripe is sweet and easy to eat
Overripe is sweet but is too soft and is extremely mushy and quite the mess to hold in your hand
Btw I just ate a ripe banana a few moments ago
