I've been using F.lux for over seven years. Advantages… - You have a great deal of control over the blue level. Night Shift's blue level is higher than F.lux's default, and not adjustable. - Flux transitions more naturally as the sun goes down. - More scheduling options, "disable until tomorrow". - the big one: disabling per-app or for full-screen apps. You probably don't want Flux on while watching a movie or binging on a videogame. (I set up my lady friend with Night Shift and watched a movie with her recently, spent the whole film wondering why they made such awful color choices)

- Night Shift is disabled for external displays. That's another killer one.

  I use Night Shift on my external 4K LG monitor no problem.

  NightShift absolutely works on external displays

First point is incorrect. Night Shift's color temperature is adjustable, which includes the blue level.

  While the color temperature is adjustable, I've found (anecdotally) that the warmest setting on Night shift is still quite a bit more blue compared to the max warmness on F.lux. (Tested on iMac and MacBook Air, may be different for other screens)
