Religions are packages of ideas. As you've said, people ascribe to these ideas at varying levels, and there are many variables that may affect their level of adherence to their religion's tenets (poverty, as you've said, being a big one.) While I'll grant you it's possible that different religions, that is different packages of ideas, could be comprised of ideas which sum to the exact same amount of good/bad influence, it's clearly not the likely case that any two religions, much less all religions have the exact same moral value (you may want to argue that how one measures moral value cannot be divorced from their bias, but this is besides the point, whatever the scale, the point being made here is not diminished.) So while there of course are extrinsic forces at play, the idea that the content of the package of ideas has no bearing on the resulting actions of its adherents is on its face absurd.

While I do think Islam is a worse set of ideas than Christianity, which is a worse set of ideas than Buddhism, I implore you to first deal with the point above independently. If you then disagree on which religion is worse, that's fine-- but it's intellectually repulsive to conveniently pretend different religions don't produce different outcomes or that their differences are purely topical and aesthetic.
