When it comes to UPS highest efficiency should not be the main driver. That is just plain silly. The main driver is RELIABILITY and AVAILABILITY, otherwise you won't or shouldn't be bothering with UPS in the first place.

Some clients want to have cake and eat it too. The transformerless units offer higher efficiency and relatively similar reliability.
