I actually cut one of my BUS Alolan Ninetales for one of the Evosoda (-1 BUS Alolan Ninetales, -2 Kukui, +3 Soda). This is my personal preference/playstyle, but I feel that Alolan Ninetales BUS and Alolan Ninetales GX are two completely different deck directions. If you're planning for the BUS wall, why play any GXs? Outside of maybe 1 Lele on bench to get Brigette, adding more GXs to the field just ruins the defense of BUS. Even if your opponent is running 1 or 2 tech Pokemon to out you, you're not going to lose with 2 to 3 BUS Alolan Ninetales on your side. For example, if you battled my deck and I layed out my BUS, your 2 BUS would just roll over my 1 copy anyway. I would honestly go ahead and flip the ratio to 2/3 GX/BUS if you want to go for the slow & steady but near certain win. The only thing that can guarantee wins against BUS is Meta(ng)google GX, but that deck is GG against any Alolan Ninetales build. And if you're playing GX's, investing energy into BUS to attack just takes away from Blizzard Edge, so I only use one to act as a shield as I charge up my GX's, then Float stone/Guzma/Retreat + Aqua Patch that sucker out of there, and if I set up fast enough I don't even need that. When I can have a turn 2 Alolan Ninetales GX with a DCE on it in my active, I'd rather go for that.
I don't know if I'm composing my thoughts well enough, but basically I think that GX and BUS contradict one another. I would personally pick one to focus on, and the other one just run 1 or 2 of as a failsafe. Speaking for myself, the only thing that stops me from going straight 4/4 BUS for nearly guaranteed wins is that it's a boring way to both win and lose.
And just personally, I'm never worried about the 1 card prize. Prizing is just a mandatory risk that's part of the game. Since my build is focused on winning off of Alolan Ninetales GX, my primary strategy is never compromised by prizing the BUS.
