This depends very much on the type of UPS. Big, high dollar UPSes will convert the AC to DC and back to AC, which gives amazing pure sine wave power.
The $99 850VA APC you get from Office Depot does not do this. It switches from AC to battery very quickly, but it doesn't really do power conditioning.
If you can afford the good ones, they genuinely improve reliability of your hardware over the long term. Clean power is great.
