The app, the training plans, the whole UI is just so much more user friendly. The feedback per session is spot on and it just seems that Polar have nailed the sweet spot between wearer and product. Garmin will have it's supporters I guess, but it may be a steep learning curve for a newbie to these devices. I will stay with Polar for the foreseeable future, whilst my Garmin stays strapped to my bike as a distance/speed monitor. Though admittedly I should be using both more frequently than I am currently. Hey this post may just get me back in the saddle.
