This is definitely subjective. While you find mouse acceleration on Macs miserable, I find mouse acceleration on anything _but_ Macs miserable (looking at you especially, Linux/Mutter).
I'm mostly commenting on acceleration in gaming. The acceleration alone doesn't bother me for productivity. However, for gaming it doesn't matter what platform you are on acceleration sucks. Technically a subjective opinion but its pretty close to a consensus for anyone that plays 3d action games where you control the camera and/or your crosshairs with a mouse.
