I’m using Memmy and Mlem. So far I’m liking Memmy a bit better because I think it has more features (though part of that is likely just me being an idiot and missing things in plain sight). I feel like Memmy is easier to navigate, and it displays useful post/comment information better. That said, there are definitely a few things that make more sense on Mlem. I also really like how close Mlem is to Apollo. Right now, they’re both fairly buggy in their own ways (Mlem more than Memmy), so I just use whichever one has the feature I need at the time.
