Microsoft Edge is so disappointing because it was and can be a great browser.
I recently had to use a low-spec computer (Celeron 6305, 4GB Ram, Windows 11), and Firefox just did not run well on it. I switched over to Edge and it loaded webpages much faster, and used much less RAM and CPU while doing it.
The problem was I also had to go into the setting and turn at least 10 different things off. Shopping assistants, copilot, sidebars, etc. The average user is not going to know or feel comfortable turning all of these "features" off, leaving them a browser constantly showing them adware and sending tons of data off to Microsoft.
TLDR: On low-end computers Edge runs great, but Microsoft has also injected it with a bunch of crap.
I would be tempted to switch to edge for the sake of "super duper secure mode" [1] but they have violated my trust in so many ways that I can't bring myself to do it.
You can disable JIT in Chrome (which also enables CET [1], just like in Edge) by executing it with
--js-flags="--jitless"
You can also disable JIT in Firefox by setting javascript.options.baselinejit, javascript.options.ion and javascript.options.native_regexp to false in about:config, although you won't get CET.
