I'm definitely gonna get shit on for saying this but I hated Kids WB at first because it was a local channel (well, it played on whatever local WB channel you had) and we didn't get local channels for a few formative years of my childhood.
When we finally did get it, our local WB station decided to split Kids WB in half. Two hours Saturday, two hours Sunday. And the best shows* (Yu-Gi-Oh! and Pokémon) were on Sunday, when I was at Sunday School. So I had to record eps with a VHS recorder and PRAY no one used the kitchen TV while I was gone. I hated that the shows I wanted to see weren't just on Cartoon Network/Toonami.
But aside from all the channel-specific shit, Kids' WB was a solid block. Aside from the anime it had, I liked R.L Stein's Nightmare Room, Ozzy and Drix, and The Mummy Animated Series (which was surprisingly great.)
I was introduced to Tiny Toons on Nick, and Pinky/Brain, Batman TAS, and Batman Beyond on CN. Kids WB did have Static Shock which I always thought was cool, mostly for the theme song. Actually how much I liked a cartoon is pretty closely correlated with how good its opening was.
* Regardless of how you feel about shitty childrens' anime, by the time YGO and Pokemon were airing I think everyone can agree it was already a shell of its former self.
