I have used AOS4.x a little bit on the "classics" and could tell you that (forget about price and all those issues) the good news is that they did a remarkable job of making an 3.9 + Visual Prefs, Birdie2000 and MUI type of system work a whole lot easier, stable and quick, even on these old PPC machines.
The bad news is they did a remarkable job of making an 3.9 + Visual Prefs, Birdie2000 and MUI type of system work a whole lot easier, stable and quick, even on these old PPC machines.
Meaning, they would not break ranks and move on to offer something very new and different. And that is partly all our fault, sending the wrong messages that it should be a very 68K AOS but just faster and with more Aminet junk added on.
So, to me, they did a good job giving you what you asked for, as a 'community' voice / consensus.
I will never really go for the rabble of "NG Amiga" banter. They are lost. Amiga 68K however is finally picking up steam like the C64 scene and I'm reading about Assembly language! That crap is hard...
