Fitness Wristbands

I Am on the market for the RIGHT fitness wristband.  Not the coolest.  Not the cheapest, nor the most expensive.  Not the cutest.  The RIGHT one.

I am leaning more and more toward the Fitbit Flex. The specs are nicee ( http://www.fitbit.com/flex/specs ) and it seems to fit all of what I am needing and wanting.

But what do you guys think?  Which ones do you all have and what do you like about them?  Please comment, because I Would LOVE some feedback.  I am planning on purchasing one this weekend.  I just want to make sure I pick the best one for me!

Thanks in advance.
