My favorite Batman arc would still be Hush.
I liked the Knightfall arc too, because it proves that there can only be one Batman and that person is Bruce. Az-Bat did beat Bane but his tenure as Batman seemed a bit wild and chaotic. Good thing Bruce recovered from his injuries and schooled Jean-Paul.
Dick as the new Batman is good but IMHO, I think that Tim would have been more suited, since his detective skills are better. But I guess Damian would be a pain in the ass if he was Tim's Robin.
For animation, I really liked Batman: the Aminated Series. I enjoyed Batman Beyond too and I've also seen a few episodes of the recent The Batman.
I have some Mattel Batman figs in my collection and I also wanted to collect the DC Direct Hush line but they were quite pricey that time.
