My favourite things have been seeing on the daily heart rate graph the moment my favourite band at a festival came on, and the time I had a horrific nightmare.
I also noticed that excercises that I thought were pushing my heart rate to its peak ~180 (i.e. my upwards slog of a bike ride home, or going to the climbing gym) were actually moderately intensive, topping out at like ~130 (although, the absolute accuracy of the cheap HR sensors is questionable: but they're fairly good at detecting relative change). It encouraged me to do more cardio-intensive running mostly just to make the numbers go up.
Also the sleep tracking (again, might not be the most accurate) yields some interesting data. And being able to see the effects of consuming various substances on HR.....
Some of us just geek out over Quantified Self :-)
Also of note: I always felt that the Fitbits are too much of a "walled garden"; the devices' bluetooth communications are locked down and encrypted so only the official app can do anything useful with them. After I went through three broken/lost fitbits I switched to Xiaomi mi bands and the fact that they've had their communications protocol reverse engineered and a really powerful third-party phone app "Notify & Fitness" is great for me as I can play around with the (live!) data coming off the band, without the condition that it touches anyone elses' servers first.
I've also used the band to sync an LED pixel array tshirt I made to my heart rate
