Does anyone use this? Is it worth looking into or is it not more secure than just using VPN and TOR on your machine?

If you're asking about using TAILS on a raspberry pi, you can't because you need an x86 processor and i'm pretty sure the pi's use ARM.

Do you want to use your raspberry pi as your main computer?

A nice vpn and antivirus software on any computer should help protect you, just make sure your OPSEC is good because that's what could possibly hurt you.
