They are pretty robust nowadays: the last kernel race I can recall that could lead to incorrect data was found a few years ago now.
But they are not designed to be efficient if they grow large or if you have many of them; and make sure they never run out of space (use the snapshot_autoextend* lvm.conf settings / --monitor y / dmeventd).
