happily, please, yes.

The browser caches pretty much everything but the HTML, so the payload is minimal. A fast SSR site is a dream compared to the myriad poorly implemented SPAs out there.

It's ridiculous going to, for example, an airline site; trying to book a flight and discovering that the damn reservation process is borked due to an uncaught exception in the latest update to the SPA (in which case the house of cards collapses, fun).

With an SSR the JS footprint is much smaller, which can lead to more stable/reliable apps.

I find the modern web to be a complete mess, but the loading spinners are nice, provided that the loading actually finishes (if it doesn't, look in the console and you'll likely find your answer in red).
