Jarv vs. Polar (H7?) HRM

Options
Hi all..

I've been using/tracking with MFP since February and have lost almost 30 lbs so far. I've started a running program to get the exercise part of the (eat right, exercise) equation. I think an HRM would be a valuable addition to my workouts and I love tech (ok, so I'm a little geeky).

I am pretty sure I've nailed down my options to the Polar H7 and the Jarv. They are about $15 different at this time (thanks Amazon!) and I'm wondering which is the better option. I've seen good and bad reviews for both, although on Amazon at least, there are about 500 reviews for the two Jarv HRMs (iOS and Android) and around 1000 for the Polar H7.

Anyone have a strong opinion about which would be the better option or are they both equal?

Thanks for your input!!
