The E-3 is a dinosaur.

The E-7 Wedgetail is a vastly more capable platform than the Erieye/GlobalEye in pretty much every way, but costs four times as much, and there are other issues with Canada and Boeing as have been pointed out by another commenter.

Delivery schedules are also likely a factor. Assuming the USAF actually orders the E-7, they'll probably get first priority on the Boeing production line. Any export orders would have to wait.

The airframe itself, perhaps. As for the radar, that remains to be seen. The E-7 uses an L-band AESA radar, whereas the GlobalEye's radar operates in the higher-frequency S-band. In general, higher frequencies are better for engaging smaller/faster targets, but perform worse in adverse weather conditions.

It's been a long time since I took my electronic warfare courses, but in a situation where the radar is expected to spot small drones and other targets I would prefer a higher frequency radar.

It should be noted that the US military itself didn't want the Wedgetail in favor of a space-based solution, until Hegseth forced them for publicity reasons.
