Wired gps receiver signal strenth versus Bluetooth

[SFTreo650]

Hello all,
There are many databases comparing wired vs. wired gps receivers and bluetooth vs. bluetooth, but how does the best wired receiver stack up against the best bluetooth? Am I wrong, but are all the wired receivers using SiRF II and the BT using SiRF III now? What difference does this make?

Finally, what is the latest and greatest wired gps receiver nowadays?

Thanks for any input.
