What is more secure: EAP-PEAP, EAP-TLS or EAP-TTLS?

If your concern is about to authenticate devices (smartphones) and not
users for sure (think of stolen phones), Client certificates should do
EAP-TLS seems to be suitable and is ready to use with a FreeRadius Fresh
install as I know (I don't use).
Note for EAP-TTLS:
You should not use PAP under TTLS as a Radius admin can see users
passwords in debug mode (and even log them).
I prefer challenges based methods (eg. MSCHAPv2) for user interactive auths.
Hello Adam, thanks for the answer!! :)
At first our freeradius server will be configured for authentication of
smartphones from our wifi network. My intent is to try and configure each
client to have their own certificate for the connection.
Scenario 1 (in tests)
I already have a scenario with EAP-PEAP where the client downloads the CA,
installs it on his smartphone and connects, but as we know, if he does not
select the CA at the time of connection, he will still be able to connect.
In this way we are in the hands of the user's "willingness" to use the CA,
even informing the danger of not using the CA.
Scenario 2 (intended)
As mentioned above, I would like a scenario where the client had its own
certificate and the radius server verified this certificate in
authentication. If it is signed by the CA of the server, it authenticates,
For scenario 2, what is the best method?
