What Adblock do you use with Safari? I would also like to try switching from Firefox to Safari but I haven’t found anything that can compete with uBO
Adguard [1] is a decent free option.
I also use a Pi-hole [2] on my network. That blocks ads in apps (not in the browser) like Letterboxd for example.

I use UBO on Chrome and find the above experience comparable.
Worth noting they continue to have a lifetime plan.
