The Gripen is a more modern airframe than the F16 with a better performance and should be at least as good electronically as the F16. As you mention it is designed to be easier to maintain than the F16 and was also designed from the start to operate from roads and other temporary surfaces.The main benefit I see with the Gripen is the potential that it could be easier to support with limited/rapidly trained technicians.
However what hasn't been advertised as much, and could be its biggest advantage is the Ukraine have been given the use of some Saab 340 AEW aircraft. There is a data link that exists between the Saab 340 and the Gripen. This will give Ukraine an unmatched advantage in the air war against Russia who don't I believe have this capability.
