I prefer smaller commits to larger ones because it isolates things (both improvements and breakage). I use git bisect when needed. You can always squash small commits into larger ones if really necessary, but teasing apart large commits into small, logical steps or components is much harder. Smaller commits are more "mobile" in that they can be cherry picked (in or out).
