Same country at least - the iCloud Private Relay options, iOS:
“1: Maintain general location
2: Use country and time zone
Maintain your general location to receive localized content, or enhance your privacy by using a broader IP address based on your country and time zone.
Safari Private Browsing always uses an IP location from your country and time zone.”
As for what's different: We're a Multi-*Party* Relays (vs. traditional VPNs which are Single-Party Relays): https://www.privacyguides.org/articles/2024/11/17/where-are-...
With Multi-Party Relays you no longer have a trust a single entity not being malicious or compromised. More on this here: https://obscura.com/#how
Also, all our apps are open-source as well: https://github.com/Sovereign-Engineering/obscuravpn-client
