Line interactive versus on-line UPS

An IBM business partner recommended a 3000VA APC Smart-UPS to replace the
UPS serving our migration tower but when I called a vendor for a quote, the
vendor said he wouldn't recommend a Smart-UPS as they are "line interactive"
units.  Vendor is suggesting an on-line type UPS which costs more but
delivers cleaner power.

Do any of you use line interactive UPS's?  Isn't it better to spend a little
more for an on-line unit that delivers cleaner power?
