I mainly just wanted to try Kbin after having already tried Lemmy before.

Literally was that Kbin started with the letter K, and thus matched with my going DE, KDE. So really just a matter of taste I guess. I always recommend people to use what they like.

On top of elements already mentioned by others, an initial draw for me was the tenor of exchanges I was seeing on kbin. Of course the instances all interflow and I won't claim that Lemmy instances are not the same. But that was my initial experience. I like having a home base where there's some effort made to be communal and give thought out answers.

I set up both, and kbin was up while I couldn't get on world for 36 hours. Granted it turns out I had to just quit the app to get it loading but I didn't know that for a couple days and kbin worked fine

I was introduced to kbin first, and after giving both kbin and lemmy a shot, I decided on kbin as my primary. I prefer the layout mostly. Yes I know you can customize lemmy to get it to a similar look and feel, but kbin feels great straight out the box. The Mastodon integration is interesting, and its nice to keep up with what's going on there at the same time on one site. Also as federation users, we are encouraged to join smaller instances to lighten the load of ml and world, and kbin seems to be a good compromise of joining a smaller instance that isn't too empty. Also, with the recent hacks happening with the bigger lemmy instances, I feel like I made the right call sticking around here.
