I've had the Zeo for about 5 days, so I can only provide feedback relative to that amount of time. It certainly SEEMS accurate with it's recording of my deep/rem/light sleep cycles. There's no way for me to really know though since I'm asleep.

I'm a data fiend, so having the data is worth more to me than the smart-wake feature. I cant speak for the WakeMate, but the Zeo will wake you up to 30 minutes before your target time if it is more optimal than your target time. I've not experienced any benefit from this so far, but like I said, only 5 days use.
