I guess they have that too... but the main thing in my mind is the fact that a Fitbit can run for days on a single charge while the Apple Watch only gets ~14 hours

Yeah the Fitbit definitely benefits from having less features to drain battery and if you're the kind of person to utilize the sleep tracker on the Apple watch then you'd need longer battery life.
