Hello, a couple of things that I can think of:

1. Transport protocol is different for both. RADIUS uses UDP and TACACS uses TCP.

2. Accounting is limited on TACACS, and it is extensive on RADIUS.

3. RADIUS is an open/rfc standard, and TACACS is mostly intended for CISCO devices.

Hope this helps!
