Not always. SSR that needs to run JavaScript hydration needs to download more content (the html and js bundle) than a spa before it’s interactive. I don’t know why the community collectively decided that first-contentful-paint is a more important metric than time-to-interactive. Seeing a page quickly and waiting a noticeable amount of time for it be functional seems like the worst possible ux, especially when there is no signal to the user when the JS has loaded.
