You certainly aren’t alone. The Batman is THE best animated Batman series. It better than BTAS, by quite a bit IMO. BTBATB was fun and I liked its tongue in cheek campiness.
The Batman is a better visual style, the fight choreography is much better. BTAS. by Bruce Timm’s own words was brawler style, which doesn’t suit the character nearly as well as more fluid fighting style.
Joker was a malevolent interpretation. Much better than BTAS. I liked the take on Riddler, it was very fresh. I quite prefer the Mr. Freeze version. (The oh so pitiable Victor Freeze from BTAS left me cold. Pardon the pun.) I liked their being a history between the Cobblepot’s & the Pennyworth’s. That was very really nice angle I’d never seen explored. This Penguin came the closest to Burgess Meridith’s Penguin. (I did love Paul Williams in the role in BTAS)
Their use of bringing in Batgirl first and as older than Robin made much more sense and more comics accurate, calling back to the Bronze Age.
Rino Romano is a better Batman voice than Kevin Conroy. (If there is a truly hot take about the series it’s that). KC was a good Batman voice but I never felt the Bruce Wayne side. Where as Rino’s work was much more balanced and I the idea that they were 2 different voices but had similarities as well, especially cadence. His Bruce actually sounded like the voice of someone who went to upper class school system but had traveled extensively as well. And the since of dry comedy, which Bruce as a character would have picked up naturally from Alfred.
I’m not sure if it’s still on the service or got rotated out, but Batman vs Dracula is great and based on The Batman characters as well.
