How do you measure the "betterness"?
Statistics is a good tool to decide to get on an airplane--the
large-numbers info is that it's much safer per passenger-mile than
driving in cars.
Statistics doesn't provide much comfort once your wings slap together
at angels-10 and you plummet into the ocean.
Occam's razor: don't complicate theories beyond necessity. Sounds
good. OK, say my theory of everything (TOE) is: "God did it." Hard to
get simpler than that, no? You say your necessity is different from
mine? *Ah...* QED.
Or as my Daddy never said, Occam's razor can't shave the Spanish
Barber.
