You generally get what you pay for with UPSes.
The differences lie in:
1) Resistance to abnormal power supply, lightning strikes etc. More
expensive UPS is better protected.
2) Efficiency of supply. Power is wasted in the conversion from batter
to 240Volts for your computer. A more expensive UPS will waste less.
3) RF interference. A more expensive UPS will cause less RF interference.

Kind Regards
