While racing ABS systems are better than street ones, street ABS will be hard to out-do manually. If the ABS system does not pulse out individual wheels you might be able to beat it manually because it would be giving up some braking force on the wheel with more grip.

However, on snow, ice or gravel it is not a good idea to use ABS if you want to stop anytime soon. The reason is that the plowing/sliding effective friction coefficient is greater than the rolling/static coefficient of friction. Note that this is a complete reversal of the dry road situation (or even the wet road situation).

So, since you mentioned snow, I would say you are doing the right thing pulling the fuse.
