Sounds like Photon might be the one you're looking for: https://phtn.app/

Some of the alt UIs mentioned in this thread can be test-driven on lemmy.world:

• a.lemmy.world is running Alexandrite
• old.lemmy.world is running Mlmym
• p.lemmy.world is running Photon

And as others have said, once you find one you like you can self-host it and use it with any instance you prefer.

Or if you like the old Reddit style: https://github.com/rystaf/mlmym

I use Alexandrite. It works like my brain wants it to work, makes good use of wide display, has keyboard shortcuts, automatically opens external links in a new tab, and can be self hosted (if you want... I do).

There are quite a few options.

A popular one is https://phtn.app/

This thread has some more suggestions.

I've been using Mlmym.

But sadly the official Mlmym site doesn't seem to be up anymore but https://o.opnxng.com/ still host an instance.
