lower sense is always more smooth and precise on smaller targets. With enough practice on higher sens you can erase most of the imprecision, but lower sens should still be marginally better. 90cm/360 would not work for tracking fast moving targets at closer range and would suffer from a lot more inertia, which makes tracking fast ADAD movements a lot harder. You can get away with such a low sens in BFV because targets can't ADAD spam really quickly, and then with accel you can do quick 180s to snap to targets around you. CSGO players do not need to do such quick snaps because they would be dead if a player comes from behind, which is why the most players use very low sens. They simply don't need the benefit of higher sens. If you want to be a versatile player, go for higher/medium sense around20-35cm. If you want to specialize in more tactical shooters or in more tactical playstyles, then lower sens is better (but honestly just slightly).
