ANT+ or Bluetooth?

I have an iPhone 4S and Cyclemeter. I'd like to start monitoring my heart rate and cadence.

There are Bluetooth heartrate straps and speed/cadence sensors (I'm looking at the Wahoo units) and there are also ANT+ straps and sensors plus an ANT+ key dongle for the iPhone. Can you recommend which protocol to choose? Are there brands you prefer?

I'd like to have the least drain on the iPhone battery, in addition to simple and reliable operation. Thanks!
