Does anybody use Tor for everything? I'd be interested in hearing their experience if so. There are sites that I have been unable to get working in tor, usually due to the browser. Some services actively block it. There's also a performance hit.
Also, while you should always assume your traffic is open to inspection/modification before it reaches its destination, this is more likely to happen with tor, not less likely. The Tor browser does help here, by not easily allowing obvious mistakes like using http.

This happens, most of the time because of Cloudflare. A solution is to get a new Tor circuit 3-5 times, and then the page will load. If a site simply won't work, like Meta platforms I won't use them. Using alternative front-ends[1] makes most sites that usually wouldn't work, work as well.

This is false, HTTPS only is enabled by default in Tor Browser. It's common knowledge for everyone including users of Google Chrome and Firefox to not use HTTP sites.
