There are probably only a couple of dozen mathematicians in the entire
world who are really competent to argue about the relative merits of the
concepts underlying each algorithm.  I'm not one of them.  I doubt any
of them are on this list.

For the rest of us, it's kind of like wondering whether King Kong or
Godzilla is better at terrorizing urban centers.  It's an interesting
thought experiment, but we'll probably never reach a consensus.  All
we'll be certain of is that if we need an urban megalopolis thoroughly
cowed, either of the two will do the job just fine.
