Use both.
Lemmy is still way too buggy/bad design, more specifically:
-New posts loaded dynamically even when I'm not sorted by new. Just give me a static page, servers are overloaded as it is, why do so many requests for a shit UX? If I'm sorting by hot I don't want to see new posts.
-Not desktop friendly (too much whitespace)
-If I click on a post then it often shows some other post but with the comments of the post I clicked on
-very slow posting
No longer the case on current day reddit, but in the past in the news subreddits, when an article was clickbait one of the top comments would usually point out that it was click bait and why. And that made reddit for me a very useful source to get news from all over the world because it was easy to skip through the biased/clickbait articles.
Then also the specific gaming communities. Lemmy is far to small to have a community for every single game so that's a big loss for me.
