I have been using a Fitbit Surge for a little over a year.  Unfortunately, the Surge was a bit of a dud in the design category.  It was one of the few FitBits without a replaceable band... and guess what broke today.  If you guess the band, then you get a gold star.

Anyway, I like the software quite a bit and I especially like the sleep tracking features, which I really need.  So I picked up the cheaper, but more useful Charge 2 to replace my on the way out Surge.

This one also has the hourly reminder to get up and move.  Another thing I need.
