Religions compete by "virality", like viruses they evolve towards encouraging reproduction.
Even if you measure "better" as "more viral" - it's not "gods" who are better - it's cultural memes (for example there's 1000 versions of christianity believing in the same gods with vastly different cultures and virality outcomes).
