I have had a Linksys, D-link and AEBS. The airport was the quickest and easiest to set up. I can't say how better it is as the Linksys was in a house in the UK, timber frame, the D-link in Germany with lots of concrete and the airport in Canada with timber again.
My feeling is that the range is similar but ease of use wins for me specially as I get >270 on my MBP connection and a reliable 56 on a Viao anywhere in the house.
