After using HTMX for some time with different frameworks, I've come to prefer Go + Templ + HTMX. Good match between versatility and simplicity!
I feel like Go is quite verbose and defining templates in Templ feels painful.
there's a performance increase too, but these apps I'm talking about are so simple it's not enough to really notice. objectively FastAPI is really good and makes running a simple site so easy, I'd still recommend to most people using that.
