Safari requires MacOS and thus isn't a replacement unless you exclusively use Macs. Also, for all its supposed support of privacy features it doesn't allow you to use good ad blocking plugins like uBlock Origin. I only use the thing because it's the best for battery life, otherwise I think it's significantly inferior to both Chromium and Firefox.
