I wanted something that did 2.4Ghz to support the few devices that supported nothing else and 5Ghz to get out of the way of the multiple BT routers that seemed to follow me no matter what channel I opted for (I don't seem to be the only one with that gripe).
After being rather put off by the user reviews of how flaky the Netgear offerings and their support were I decided to leave the traditional network brands, given I've had crap equipment from almost all of them and tried the Asus RT-N56U - a fine choice as it turns out. Fast, stable, easy to use, can charge your iPad, attractive, small, unobtrusive, reasonably priced - what more could you ask for?
On the ADSL side I stuck a cheap TP-Link router in bridging mode - it stinks (no really gives of a scent), I lost 4Mb just like that. So I can't reccomend that.
At work I chose a Draytek Vigor 2830n and I can't fault that either, I've never seen a router apply new settings and reboot so quickly. Of course Drayteks are very business focused but you still have UPNP if you want it and the option of adding a 3G modem, a 2nd ADSL/Cable, VOIP phones(if you add the letter V), VPN's,VLAN's and a host of other nerdy delights.
