GRUNT
Packages:

FILE BASED
Good for file operations like copy/move/save. Configuration over
code. Better for small projects with small amount of files.
TONS OF PLUGINS
Most popular JS task runner. Almost any possible task is available
as plugin. You can perform build-in or custom operations. Sync/
Async

No temporary files. Code over Configuration. Much more faster
then Grunt for file-content processing operations.

You can work alone or with a team. You can work with or without
central server. Even without network connection.
FAST
You can clone whole repo/branch or just a few commits.
All meta-data is stored in one place ~/.git
