Yeah I've been looking at Blazor for some time, and the .NET 8 updates are great, but I just don't know if I like the .razor DSL and the fact that things are either SignalR (latency) or .NET runtime in the shape of WASM (huge bundle, literally the kitchen sink).
The biggest upsides to Blazor is that, as you said, greatly simplify development as you basically have only one code base to think about with Blazor Server, and you save a lot of time not worrying about the backend / frontend bridge. On the other side, there is a demon on my shoulder whispering that the customer doesn't care about developer UX, and they'd go for a native web-app over a latency-riddled or slow initial load web app.
