My experience is exactly the opposite. I've been running DD-WRT since the very first version (right when BrainSlayer forked Sveasoft Alchemy), and it's an incredible piece of software. Absolutely flawless.
Yes, it is true that the wiki has conflicting information, but it's not that hard to find a version that works well with your set up. And most routers are really hard to brick (and worst case scenario most models have JTAG in the PCB, so you can un-brick your router even from the worst mistakes).
Once you have a stable config, you'll enjoy several years of rock-solid performance - at least until you need to upgrade your router again. Rinse and repeat.
FWIW, I'm using Asus RT-N16 with DD-WRT v24-sp2 (03/17/12) kingkong, and also used WRT-350N, WRT-54G/GL. All services I use are rock-solid: VPN, QoS, DynDNS, MAC filtering, USB storage, printer support, etc. Of course, YMMV.
