For me, I consider the real test for a website's performance to be how it reacts under JS disabled conditions. Using NoScript has completely changed the way I use the internet. Combine that with DoH and filtering and you can remove a large part of the jank that fills browsers needlessly.

It's a delicate balancing act, but it puts you in control. Sometimes it's just not worth the hassle, and I suspect it's why you see many comments like "just read the f* article", except sites are so slow and cause so much rendering and CPU cycles it's just an abuse of the platform.

Websites are capable of serving text without JS being required.
