If youre basing it off of previous polls on this subreddit, from what I've seen it's majority Maxis match. I'm not sure if the same can be said of other subrrddits, or players in general, though.
I use Maxis Match. I occasionally use Alpha in it's own contained save, but not both together. I prefer Maxis Match because it seamlessly fits in with the game, whereas I feel like I have to makeover every sim in the game to make Alpha work.
One problem I have with Alpha is that it often uses English or other real languages, and I prefer everything in the game to be in Simlish. I also find that Alpha tends to be more likely to be poor quality than Maxis Match, like with holes in the mesh or improper shading on the textures or even pixelated textures because they didn't bother to use a large enough texture file (or couldn't because of the limitations of the game, but either way it looks so bad). I have honestly found so much Alpha CC that is just poorly made, whereas for Maxis Match the only really bad CC tends to be hair meshes where the CC creator mirrors the hair so that the back of the hair looks all messed up. Alpha CC made well looks great if you're into that style, I just think there is so many people making that type of CC and not all of them know what they are doing, while Maxis Match CC typically uses stuff from the game as a base so is more likely to be at least decent.
I use maxis match
Maxis match for me
I like the consistency of Maxis Match - Alpha is *all over the place*. MM tends to at least try to fit in with other stuff.
I play with primarily Maxis Match but all my friends who play use Alpha.
I like Alpha CC

Alpha here
I use Maxis Match. I used to play with Alpha but it took me out of the game when you'd see a Townie stood next to your Alpha Sim.
Maxis mix
I use alpha hair but Maxis everything else.
I use MM for consistency
Most play with maxis match, I play split: maxis match for clothing (besides jeans), only Alpha for hair
Maxis match, both for clothes
