Static pages is basically always faster. The web browser is very, very quick at rendering HTML. Executing JavaScript is much slower. But, the real benefit of static sites is caching. You can cache on the edge and have remarkably fast load times.

For the flickering or flashing, you can just stick a couple lines of CSS for view transitions and boom, done. I understand the flashing looks less professional or fast, but it’s not actually.
