Disabling JS in your mobile browser is a nice trick when you have crappy connectivity or on metered. Most of sites sort of work, but much, much faster. Ads, some paywalls, and most of cookie walls dissappear, too. It is a more relaxed, minimalist way of browsing. And if something you really care doesn't work, you can share the url with another browser.
On the flip side, it makes you painfully aware of the terrible way we have fucked the web. Sadly, most of JS code is written against user interests, serving only corporate ones.
