If you the differences in used/alloc and avail/free between zfs and zpool,
it's because they show different things.
Search the archives and the zfs-discuss archives for all the gory details.
The cliff's notes version is that zpool shows raw storage available in the
pool, and zfs shows usable storage space after redundancy is taken into
account.
