It is a rare person indeed that personally has all of the currently available smart telescopes. I don't have the Unistellar scopes and don't like to talk about what I don't have. I do have the Vespera, Dwarf2, and SeeStar. I have found things that each of them excel at as well as overlap in functionality.
I think both the Vespera and SeeStar beat the Dwarf2 for astronomy although the Dwarf2 is the winner for daytime landscape or nature/wildlife photography. So I mainly use my Dwarf2 for daytime usage. I'll add a Dwarf2 image below.
With the slightly longer focal-length, I think the SeeStar is slightly better than the Vespera on the small things as well as sun and moon.
The Vespera has a nice built-in mosaic mode and really shines on the wide FOV and is my goto instrument when I want to capture things like Orion/Running man, California nebula, Horse Head/Flame, Veil, Heart, Soul, Andromeda, or any of the other larger targets. Vaonis also recently made a limited run on a modified Vespera (Passenger model) where they put in a larger sensor for an even larger FOV but they have sold all of those already. There might be some that got it that might then want to sell their original Vespera so some original Vesperas may be showing up on the used market soon. Vaonis is also coming out with a Vespera-pro model next year (May onwards) that will be F5 (250mm focal-length) and use a larger sensor with smaller pixels to do better on the smaller DSOs. Unistellar may also have some new scope models in the works but nothing announced yet to my knowledge.
With a little searching, you can find lots of examples from each of the available scopes.
Most people don't post wildlife photography so I'll add one here.

And also, the following is an example of what the SeeStar can do for daytime photography. I aimed it at some broken chimney parts in a vacant lot across the street from me. This is right out of the SeeStar withy no post-processing.
