I am a crazy cat mom and I have a running water fountain for them. Zeke loves running water (runs to the bathroom whenever he thinks anyone is going to turn on the shower) and used to even shower with me as a kitten. I've read cats in general prefer running water and because of my experience with Zeke I just knuckled under and went for the fountain. (If I turn off the fountain after a few days Zeke gets really, really aggressive about chasing down running water sources. Also, my parents spoil him (turn on the tap for him in the bathroom) which hasn't improved his insistence.) I have heard wet is bad for their teeth, potentially? I had a roommate with a cat who developed hives if she ate non-grain-free food.
I had a cat that would also get in the shower with me every morning! And he really loved ice cubes.
I've also heard dry food is bad for their teeth. There's no winning with their teeth lol. My tortie got very stinky at one point from tooth delay.
