SVN's locking ain't so amazing, it must be said, because it's clearly not the way it's intended to work. But it's better than nothing, certainly, and TortoiseSVN on Windows has some nice features that make it work fairly well.

Another issue is the filling of your hard drive with crap - obviously git keeps the entire repository locally, and SVN keeps a previous revision (I think?), which is a bit useless for enormous hundreds-of-gigabytes repositories mostly filled with stuff that's not significantly further compressible. To add insult to injury, git then spits in your face by not letting you retrieve only part of the repository! - well, obviously the problem is that git just isn't designed for this kind of thing, not that its decisions are unreasonable. Shame, though... some kind of binaries-and-locking support would be nice. It would be great to be able to use git for everything.

You can create a git repository that has other git repositories in it (submodules) but you can't checkout an arbitrary subtree of a git repository. I spent a long amount of time searching for this, so I know.

Now, people have written scripts that will convert a directory to a git submodule by moving history around and stuff like that, but you need to check out the whole repository first.

That makes absolutely no sense whatsoever, unless it is a troll. Nothing can be "good enough" simply by virtue of not being something else.
