Long time between followups but I'll give this a shot. I recent tested several routers one of being the Linksys WAG160N v2 Wireless N, a Netgear DG834DSP and Linksys WAG200 Wireless G. Prior to this a SMC WBRA.
The short of it is there was not much difference between the 3 when testing from the longest distances, however the WAG160N had better video performance meaning less pauses on Youtube over the 1500k ADSL 1 link.
I settled on the WAG160N due to this reason but also because I was able to get best range and eliminate dropouts with the following tweaks :
1. Roll back the firmware from 2.00.20 to 2.00.17 - increase speed and eliminate dropouts !
2. Change the wireless mode from Mixed to G only. Got an extra bar of range disabling the wireless N.
Overall reasonably happy - still could do with better range but not about to go and spend $200-$300 on a dual band router without extensive research this time.
