The primary advantage to a UPS is that in cases of sudden power loss the UPS will continue to power the computer system long enough for you to save your work.
Additionally, in environments which have problems with “dirty power”… meaning the electrical supply may have sudden spikes or dips such as in an older building or neighborhood the UPS offers a great deal more protection than a standard surge suppressor would.
