extender vs router as access point

[RMKat908]

I own a Nighthawk X6SAC3000 extender and Nighthawk AC1900 router. Which would be a better access point hard wired to my Spectrum Motorola router?

If you setup the x6s in AP mode, it'll act as a tri-band access point versus the AC1900 is going to be a dual band. 

Gives you an extra 5ghz channel to spread devices out on.
