I agree that Vancian casting was terrible (I certainly never liked it), but I strongly and emphatically disagree that AEDU was worse. This is clearly just your opinion and not a universal truth.
I don't deny that there may be a better way to build an ability system, but we have yet to see one in D&D as far as I'm concerned. Which is, of course, just my opinion.
For me, the vancian system is essential to d&d and a big part of what makes it fun. There are other ways to approach spell casting, and plenty of games have taken other cool approaches, but without that classic vancian system, which I had for the three previous editoins, it really doesnt feel like the same game to me (i am not saying it is objectively not d&d, just that for me D&D without vancian casting feels like a different game).
