UDLD detects unidirectional failure when you using fiber ports and/or devices that are connected through media converters If you are using only copper in your environment, I really don't see a reason for deploying it.
Loop Guard is usually deployed on your uplink ports concerting access to distro or distro to core.
Depends a lot on the network. If you are running VSS on Cat6k, you do not want to enable STLG (Spanning-Tree Loop Guard) as it is a STP add-on, and VSS with MEC eliminates some STP usage. UDLD is recommended, especially for fiber infrastructure. Unidirectional links are considered to be a majority root cause of all bridging loops. PS: If you run 12.2(33)SXI4 or later, then you will get Fast UDLD, which is great for subsecond unidir. link detection for redundant and critical environments. Normally, if I had to choose between the two features, I would implement UDLD.
