What kind of decisions do you want to be able to make? Unless you're writing all your own filters (in which case, kudos to you!), you're still ultimately delegating these decisions primarily to a handful of filter list maintainers you've probably never met. Brave's source code and filter lists are all developed in the open and are heavily customizable, as well.
