Hi Alkemyst,
I've run Cisco (IOS and RVs), Mikrotik, Ubiquiti, and all flavors of *WRT firmwares in my home-office, and usually notice smoother operation from IOS gear (of course), MT and UBNT (90+% of the time) and even with most revisions of Tomato and Gargoyle as long as throughput needs aren't crazy. The open-source stuff, though, is a bit more of a mixed bag when trying to find stable releases for certain firmwares, with DD-WRT being a prime example (it can be great, or an absolute mess, at random it seems... more so than any other third-party firmware I've tried - YMMV).
All in all, if you've got access to full-blown Cisco and you're comfortable in IOS, by all means stick with it for routing. I'd be apt to say the same for the Aironet, but I've also had great results with Unifi, certain EnGenius models, and other brands of managed wifi (Ruckus, even Zyxel, etc), so wifi is perhaps a little less clear-cut, but nonetheless if you can grab a 2702 for free or dirt-cheap, do it.
