For me I'll never go back to normal front-end work after doing Blazor with C#. It's the nice bits of React (reusable code) but the flexibility of never having to decide between front-end only focused code, or some back-end powered AJAX style code, that is transparently rendered for you. You never have to touch JavaScript, but there's ways to do so.
WASM is the best thing that ever happened to the web. When other major web frameworks adopt template engines that compile to WASM, we will see a shift in focus on JS heavy frameworks, and just people building things instead of fighting and trying to remember all the weird quirks of JavaScript.
I've done web dev with various other frameworks: Django, React (front-end only - no SSR), Vue, CherryPy, and a few others. Blazor is the only technology that allows me to use 1 programming language outside of HTML / CSS. You have component UI libraries like React does, so you have to think less about hand crafting HTML and can focus on per component logic / UI much like when developing with React or any "SPA Framework" out there.
You should try it out; microsoft makes good contributions to open source software, and C# is, in my view, the best (or maybe the only good) backend language put there
