UPS replacement

Ive been browsing the net to find out why UPSes have a much lower joule rating then on surge protectors. Apparently its because a "line interactive" UPS like mine has AVR technology, so it doesn't need a huge joule rating. Then I started browsing about the response rate of the AVR and I think mine might be 200ms but Im not sure. If thats correct it sounds a tad slow, but apparently a surge isnt instant, so by the time the surge gets to destructive level, the UPS should have killed the surge or flicked over to batt power
A "line interactive" is the middle of the range UPS like mine that only uses the inverter when is needed, for surges/AVR or power loss. But you can get a online UPS that always using the inverter so no change over from AC to DC as its always in DC, so Im guessing these are safer cos if the UPS fails to stop a surge, the inverter will deal with it?? But the downside to the online UPSes, is that they use more of your electricity, more things to go wrong and cost more as the inverter has to be higher qual, as it need to use a Sine Wave output.
