I a big fan of DLINK products. Never heard of the other two companies before. DLINK's main competitor is Linksys and although Linksys routers can offer more advanced configurations. Dlink routers are much more geared towards gamers, and they even provide extensive support online and phone for getting your games to run such as opening/forwarding ports. Had an old DI-604 for more than 4 years it was the best home wire router, until I switched to a WBR-2310, firmware kind of buggy but it does the job great.
