Hello Microflash, thanks for your question. I can only answer for Raivo, since at the moment Sentinel is not available for Android (Aegis) or Windows (Protecc).

What I can say is the following: - as far as I know, Raivo uses iCloud, while Sentinel uses the iCloud Keychain (secured by Apple's encryption) - Sentinel offers Folders to organize tokens - Sentinel offers multiple themes and display modes

Hope this answers your question
