I feel like the Yuzu project is just as exciting, they make progress reports just like Dolphin and it's always a pleasure to read. It might not have the level of polish of Dolphin, but give it time.
I can't speak about the other major Switch emulator, Ryujinx, because I haven't used it much. They're just as enthusiastic though, and also write regular progress updates.
eh, as a former contributor to Dolphin, and a current game developer who has worked on the Switch, I'd say Dolphin has it quite a bit easier easier -- the GX API maps pretty well to modern GPUs, the lack of programmability means shader recompilation & reverse engineering is far from as big an issue, and Dolphin doesn't have to implement from scratch a giant OS and all of its services.
Some exist, but I have to say Dolphin just hits different. There is a shocking amount of enthusiasm for that project and that gaming era.
