I got the Fit. I had the original Galaxy Gear but think the fit looks a lot nicer than new Gear. The Fit doesnt read heart rate all the time, unless you select to go into an exercise mode. I did this today walking for 90 mins on steep mountains. The results were quite good with a lot of info from lowest and max heart rate, speeds, map, altitude range etc... If you want to measure heart rate you can anytime manually.
Definitely impacts battery. But not sure by how much yet.
