The main reason for using a heated wideband sensor is that you have more flexibility on where to locate it since it does not depend on engine heat. Simple 1 or two wire sensors need engine heat to get to operating temps.

A heated sensor can be put almost anywhere in the pipe (even in the tailpipe) and it will still get a good reading. Just make sure its mounted in the top of the pipe with the electrical plug pointed upward or 30 degrees either side of straight up, so that moisture does not settle on the sensor.
