If you don't need either the wireless-N or Gigabit wired, I'd recommend sticking with the WRT54G. The stock firmware's a joke on the WNDR3700, and the dd-wrt firmware is still bleeding-edge. After getting the correct version of dd-wrt flashed to it, it works well and fairly stable. Range is approximately the same as before, which is impressive because the WNDR antennas are internal. I haven't had to do any resets because of stability issues, but it has been reset a few times due to power outages; after the resets, I've had to manually re-configure the MAC address cloning, which is required in my current situation.
On the other hand, my WRT54G (purchased in January of 2004, BTW) was rock-solid stable - it's still at work in my parents' house right now. And since i haven't been there for three months, and haven't had any phone calls from my parents about "the Internet not working" on their notebook computer, I think that's a testament to its durability. (Then again, the notebook may be currently in use as a shim to stop a table from wobbling...)
