Wipr is a simple "set it and forget it" extension. While it's not as flexible as AdGuard, it's also a lot less complicated to use because it manages the filters automatically. But it does not have a way to modify the filters.
I've never tried Ghostery, but I should check it out.
Ah, gotcha. Yeah, looks like premium handles more complex adblocking too. But in general I haven’t had any issues with the free version of AdGuard that would lead me to needing an IAP.
