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!

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

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.

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

You can give Liftoff a try
