I have no loyalty to a particular provider I go with the best deal and coverage combination when my contract is up for renewal. I will say though, this is my 1st and probably last Samsung.
Correct S9 has treble, S8 does not.
Google has added Treble to the Pixel1 but Samsung decided those of us on a year old S8 can look for a different phone provider as they don't give a damn about customers.
