Here's a list I used to find kbin.run, it's a little barebones right now but the UI is really familiar as someone who used Reddit a lot. It is mostly centralized to kbin.social right now, as more instances pop up and the main instance fixes federation it should sort itself out as long as it keeps momentum.
It's just another UI basically. I like Kbin a lot more than Lemmy aesthetically and it was easier to get used coming directly from Reddit. Also early on there was only one instance (there's like 3-5 now? I'm on Kbin.run) so it was a lot easier for people who didn't understand how it works to use.
