Which GPS to pick

Hello, I like your service and want to pick one of GPS modules you offer. Size and communication interface do not matter (I want to use it on an outdoor rover).

Which one has the best performance (time to fix & update speed & accuracy) - is it the most expensive one? I see that uBlox module comes with USB port and handy software utility to configure its behavior, but this is not a killer feature for me.

Thank you!

This GPS drotek.fr/shop/en/home/161-ublox-gps.html is the best for the moment. We work on a new version with filters on each lines of the module.
