Asset Tracker v2 Performance Reviews?

I’m interested in the Particle Asset Tracker v2 but wanted to ask others what their experience has been with the unit and more specifically the performance of the new U-Blox GPS Receiver and Antenna vs the v1 that used the Ultimate GPS receiver.

I’ve held off on buying the kit because I didn’t need the extra Electron that comes with the kit which drives the price up.

I’m testing another new GPS receiver and wondering how much better the U-Blox is.
