Основное юзабилити-отличие:
With Git LFS, new developers cloning a Git LFS-enabled repo for the first time don’t need to know anything about it. They can use «git lfs clone» to have that initial clone come down faster, but they don’t have to. «git clone» alone is all they need.
Based on my reading just now (mainly Git Annex vs. Git LFS), with Git Annex new developers cloning the repo for the first time must also remember to invoke «git annex sync —content» after cloning. They must also remember to run that same command after adding new files.
While it probably does not seem like a lot to remember (one extra command to type), in my experience adding one extra command to a workflow can impair productivity pretty signficantly — especially if people sometimes forget to run that command.
