My experience,

Summit is the closest. It feels the best to me. But it's barebones and has some hiccups. I had a comment post 14 times this morning. I have high hopes for this one though.

Connect seems the most stable and works well.

Jerboa and Liftoff both work well when they're working. But they've had some bugs and I prefer Connect to them at this point.

My recommendation is to use Connect until you get Lemmy figured out. Then try them all out.

I'm using the wefwef.app for a bit today and I like it. Feels very close to RIF, yet you still are aware of the difference. One detail I like is auto-dark mode, and that comments and subsequent replies use colors to show thread height.

I am testing out Jerboa, got a similar feel but missing a few creature comforts. Seems the developer is really working to update and smooth the roughness in the last month so I'm optimistic long term. I'd give it a try!

Former RIF user. I tried jeroba but then switched to Connect for Lemmy. Jeroba didn't quite feel right to me. So far I'm enjoying the UI of Connect.

I gave jerboa a soft try but wasn't thrilled with it. Hoping sync will be a good option when that becomes available.

Connect is pretty damn close, and in some ways even better

You can give Liftoff a try
