My anecdote: it allows much better estimate of calorie expenditure for use in weight management.
I've lost almost 60 pounds over the last two years, a bit over half with the use of Fitbit. I find the data from Fitbit let me know how active I really was which enables me to more consistently hit my weight loss goals. This generally meant either eating less or going out and exercising more to hit my daily budget.
My wife uses Fitbit in the same manner.
Fitbit isn't a panacea, but it is a piece of the puzzle. On its own the benefits are small, but it is very helpful as a component in a larger health strategy.
