Death Ward requires expending slots before you know you'll need it.
This one requires (a) expending a "known" spell, and (b) having resources left when the event happens. When it happens, it becomes a no-brainer.
This is a very, very different situation. You can reduce "needing the resource" to "dedicating the resource", but that decision gets deferred to the point when you are finally down to your last slot (do you save it for the emergency or not).
Having your reactions removed is pretty rare. Having your reactions removed and dieing doubly so.
