Better privacy of Safari can be questionable:
"Intentionally limiting ad blockers and tracking protection[edit]
Beginning in 2018, Apple made technical changes to Safari's content blocking functionality which prompted backlash from users[103] and developers[104] of ad blocking extensions, who said the changes made it impossible to offer a similar level of user protection found in other browsers. Internally, the update limited the number of blocking rules[105] which could be applied by third-party extensions, preventing the full implementation of community-developed blocklists. In response, several developers of popular ad and tracking blockers announced their products were being discontinued[106], as they were now incompatible with Safari's newly-limited content blocking features. As a matter of policy, Apple requires the use of WebKit,[107] Safari's underlying rendering engine, in all browsers developed for its iOS platform, preventing users from installing any competing product which offers full ad blocking functionality. Beginning with Safari 13, popular extensions such as UBlock Origin will no longer work."

Edit.
But for some people there can be other good reasons to choose Apple Mac.
That's good and no limiation.
It increase the performance, the breakage is reduced and also e.g. AdGuard is compatible with that system in Safari.
Safari is the best browser against tracking by default. The GrapheneOS Reddit mod test two different iPhones at same time and both are identified as same / not unique.
I wish this would be the case in Android too.
Also Apple does a lot for privacy like E2E encrypted notifications (not possible with any Android), restrictions against Ad company (with upcoming iOS 14), and more.
Browser extensions should be avoided anyway. Keyword: client side, malicious & spying extensions, attack surface, performance.
But this is a different topic
