Chewing: Temporalis vs Masseter muscle, which is better?

[Soulrack]

What chewing/mastication muscle is better to work on? Temporalis or masseter? What happens if you build one or the other? What if you hypertrophied both at the same time? There seems to be very limited information on this on the internet and it's very conflicting.

I also heard a long time ago that the temporalis builds the eyebrow ridge, is this correct? What changes would the masseter muscle cause to the skull?

For those who are curious, you can activate the temporalis by biting and "sliding" the jaw back (Direct the bite force backwards) or the masseter by biting and "sliding" the jaw forward (direct the bite force forwards).
