Flexclone = clone the volume with its content = leaves the original LUN and is fast and you can split the clone later if needed or throw it away
SnapRestore = restoring the LUN from a snapshot by change the pointers in the filesystem according to the blockmap = can take a long time and overwrites the content in the volume. Can also degrade performance until the snapshots are cycled through once
I'd always prefer FlexClone over SnapRestore.

FlexClone operation may use snapshot, netapp create temporary snapshot, or use snapshot, which already created. (File level FlexClone)
and as i understand, creation FlexClone "change the pointers in the filesystem according to the blockmap" too?
