If Not for DD-WRT Routers like the WRT-54G would never be forgotten short time after heir release.
On the other-hand todays Wireless Routers do not benefit much (or at all ) from DD-WRT).
That said DD-WRT has numerous amount of features that are Not present in may stock firmwares.
My suggestion is to use DD-WRT if a feature is badly needed and it not in existence in the stock firmware.
The Merlin firmware for the N66U is a good choice because it is basically the Stock firmware with some minor refinement.
