You'd probably be a good person without your religion, so I'm not convinced that I should give any credit to your religion. Probably more credit goes to who raised you.

There are many ways to slice that, but in any case, it's NOT symmetric. To the extent that religious people "donate" more, it's only because one of their primary outlets for self-expression happens to be considered a charity!
My previous church expected full members to tithe (not required, but strong social pressure). And that counted as "charity" even though the vast majority of that money only benefited us (worship space and a pastor eats up a huge percentage of funds). I'm sober-minded about the fact that this space was really for ourselves, no matter how charitable the intent.
However, membership dues in my local hackerspace (where we also do some charity, but where again the vast majority of funds go towards infrastructure for ourselves) aren't considered donations. Those are dues, not tithes (aka donations).
In any case, as someone who tithed for years, IMO maybe 10% of tithing goes to truly charitable causes. Maybe.
So when I hear "Christians donate more to charity!" and then read "but effect disappears with tithing is excluded", what I really hear is "we spend lots of money maintaining our clubhouses". Not because I'm judgemental or anything, but because I've seen both church and other non-profit entities finances. It's just the reality of most community-organized non-profits that don't have explicit charitable goals as their primary intent.
So, to be clear, there's nothing wrong with funding a space and your pastor's salary (or, for that matter, paying to lodge for out-of-town hackers/lecturers). But the asymmetry in how those are accounted comes with hopefully clear entailments about any purported higher moral ground for one over the other.
As if donations were a measurement of personal quality anyway...
A lot of religious institutions tell followers that charity is required by God, and doing charity would make them more liked by God (and hence you will get a better treatment in after-life). This makes it very difficult to compare the data across the two groups.
It's part of the culture of religion. It isn't per se a measure of goodness.
