I personally find the idea of organized religions unappealing.
It's always said that people have some void or longing in them that religion supposedly fits, but how can something so important and influential to you come from the mouth of another person?
The way I see it a persons security in their spirituality should come from within, to find what they believe in themselves and not become part of a group wherein you don't agree with many of their teachings.
To pick and choose core aspects and ideals out of other religions or simply ideas to find what aligns well with your ideals seems the most satisfying and concrete way to settle any internal debate you may have about your calling or soul driven longing.
That said, personally I am SBNR (spiritual but not religious)
