The objection is that you have 5 major world religions to choose from, there could be 1,000 to 1,000,000 minor religions to choose from, the gatekeeper of heaven might be selecting only non-believers who non-believe for the right reason, the gatekeeper of heaven might have an even more arbitrary or unpredictable criteria than laid out by your geographically predetermined choice of religion. The religion could represent actual spiritual phenomenon, but the entities could have lied about who they are or what's to be expected. Not to mention that we could be a random occurrence of life in a universe created for a set of aliens we could never meet. The wager is flawed because you have to consider a near infinite number of evidence-less hypothesis about getting to heaven, which might not exist or might not even have a gatekeeper.
