Interesting article comparing the accuracy of different GPS watches. It's a bit outdated (3 years) but does show how the accuracy wildly varies from device to device.

I would question the relevance of those footpod scores for orienteering.

The footpods are obviously irrelevant but the other data is still interesting.
The GPS chipsets in modern cell phones are actually very impressive indeed, with simultaneous processing of GPS/Glonass/Galileo + chinese (& japanese?) sats, along with 2.5 and 5 GHz WiFi. The only problem is that they are programmed to be power-use optimized instead of position precision: I believe that the same chips in a standalone GPS logger with a larger battery and a good external antenna could do very well indeed.
