Searchwater AEW vs Hawkeye and Erieye AEW systems

You guys think the Searchwater is a good platform?
Dont have any data on the range. But atleast it can do over the horizon AWACS duties and C3 capabilities.
No country except the RN has operated this type of AWACS system. Thales says it can be installed in fixed wing aircrafts too.
Compare it with the E-2 Hawkeye APS-145 and the Ericsson Erieye AEW, how does it fare?
