Do magazines differ from lemmy communities? I have a Kbin account and I'd say they're the same. kbin.social/m/gaming is the same thing as lemmy.world/c/gaming.
So the difference for me would only be the UI, which looks more like reddit than lemmy does right now but that can also change in the future.

What kinda bugs me about Kbin atm are 3 things:
You can't collapse comments (really hard for mobile usage)
You have no infinite scrolling
It's less easy to spot in the feed if a magazine is from a lemmy instance or from kbin(not that it matters really but it's still nice to know)

The general look of the feed is better though with every thread having its own box. I'd also want a bit more separation of different threads on Lemmy aside from those thin and barely visible lines
