For a competitive comparison I chose the WRT610N and the 310N's direct competitor, D-Link's DIR-655. I recently tested the latest A4 version of the DIR-655 with the Intel 5300 AGN client, so its data is as apples-to-apples comparison as I can make. The WRT610N data was taken with a Linksys WPC600N client, which throws a little variation into the comparison.
As is usually the case, there is no clear winner in all locations and modes. For downlink in 20 MHz mode (Figure 17), the WRT310 / Intel 5300 AGN pair seem to have an edge at the stronger signal Locations A, B and C and even at the strong to weak signal transition Location D. But at the toughest locations E and F, there is no clear winner.

Uplink in 20 MHz mode (Figure 18) is a real mixed bag, with each of the three products taking the lead in some locations.

Switching over to 40 MHz mode, downlink (Figure 19), the only thing that's clear is that the WRT610N / WPC600N pair don't fare well at Locations E and F. But I suspect that this is more due to an advantage provided by the Intel 5300 AGN client than a weakness in the WRT610N.

And finally, with a 40 MHz channel and running uplink (Figure 20), the pattern of no clear winner across all locations continues.

The only conclusion that I can reach from this is that these three products, which occupy the top three positions in the Open Air Wireless Charts are pretty evenly matched.
