JWE is... well, it's an alternative in the same way that S/MIME is, but all
three formats do more or less the same thing, they just use different bit-
bagging techniques.  The main difference between the three is that PGP and
S/MIME use an efficient binary encoding while JWE uses a pretty inefficient
text encoding (when the RFC appeared my first reaction was "It's PEM
reinvented thirty years later").  So for:

you could say the same for JWE.
