lemmy Vs kbin?

I'm a bit confused with my options here. I am looking at Reddit alternatives and see a lot of people flocking to lemmy but it seemed like kbin was the more centrist option?

Apparently lemmy was set up by a tankie and has some CCP propaganda and other problematic background?

I have accounts with both and definitely seems like kbin is struggling compared to lemmy but that could just be because lemmy is better established? What are people's thoughts?
