Two major differences that I have always remembered are:
TACACS encrypts the entire packet, where RADIUS only encrypte the password
portion. This makes TACACS more secure.
TACACS uses TCP and RADIUS uses UDP as a transport layer protocol.
One other thing is that Authentication and Authorization are combined in
RADIUS, but in TACACS they are seperated. The seperation of AAA
functionality makes TACACS a little more flexible.
Hope this helps
David

Along with what this member said, the TACACS+ philosophy is 'security at any
cost'. RADIUS is more along the lines of 'good security but good
useability' too. You will find TACACS+ has a more granular approach
overall and a significant enhancement to Cisco products in general.
Conversely, RADIUS will be generally easier to etc.
