While I have never used a IC, I built a CFC and love it. It is NOT HARD to sanitize. Just use an autosiphon (which you REALLY ought to have anyway) to pump a bit of StarSan (or sanitizer of choice) through the inner coil while the wort is boiling. Let it sit a couple of minutes, then drain out.
Then hook up the tube to the wort and let 'er rip. Run the first bit out into the sink, then when the wort hits the end, start pouring into your fermenter, straining any hops and stuff as it comes out.
This Sat I cooled boiling wort down to chilly as fast as I can drain the wort (can't say what the temp really was, because my thermometer crapped out on me, but I normally have to close the faucet a bit to keep it from being TOO cold!)
When the wort is boiled, just run some water from the tap through the CFC to rinse the wort out, and then pump some more starsan though it.
As easy as sanitizing an IC, no, but still not hard and the chilling amount and time makes it worth it little bit more effort.
If you are handy and don't mind paying a few dollars more to build it yourself, then I'd highly recommend a CFC. An IC can chill pretty fast too, but when you add a prechiller and ice bath and all that, I'm not sure it's a cheaper way to go after all is done and said.
