Yeah, the default user agent, but those could be changed pretty easily. What else big difference have I missed?

For most of them, no. But the useragent thing is false. It is "network.http.useragent.global_override" for global (site specific is still the same as before). Though, MC didn't clearly mention it instead of just putting it in their release notes. Basilisk's addon page is also more useful than PM's which insanely check your UA (https://addons.basilisk-browser.org/extensions/).

But in my experience it is a bit harder to turn off the auto connections in Basilisk (than PM), but it is possible.

For browsers in general, I think they are just in a mess. Most of the time they (both the dev and sometimes users) don't care about telemetries that much (https://gitlab.com/librewolf-community/browser/linux/-/issues/271). And for Firefox I think they have much stronger motivations to include anti-features.
