Honestly picking programs based on lines of source code where fewer is better is quite silly. Better algorithms generally have more code, not less. Unless you're doing embedded work it essentially doesn't matter how "big" programs are.

It matters if you want to hack on them

True, to some extent. Being "big" doesn't necessarily mean it's hard to hack on, though. Emacs is huge and probably the easiest thing to hack on.
