HRM or FitBit?

I just got a Fitbit Flex and I love it so far. But I mainly bought it because I can wear it easily at work. a fairly physical job with a lot of heavy lifting & walking and I was curious about what I burn at work... but if i'd gotten it soley for the gym, I'd have probably bought a HRM. I really just wanted something to give me a ballpark idea of how my my day was going.
