As you quickly found out by yourself, each individuals hockey stick handedness comes down to personal preference, and they only wrong way is the one that feels wrong to you.
But to answer your question, numbers show that playing with your dominant hand on top is the most common way.
This may be technically/mathematically true, it certainly isn't significant from a numbers perspective. 90% of the population is left-handed, but in the US, the split is about 50/50 for hockey players shooting left vs. right. In Canada it's 60/40 left vs. right. So you are still going to have a pretty healthy percentage of right handed people that shoot right in hockey (me being one of them). I don't buy into pretty much any of the stuff on this either....like dominant hand at top....bottom hand really does nothing, etc. That's BS. Both hands needs to be working, if they aren't, you aren't a very good player. The other thing about dominant hand lower is better for shooting and the other way is better for stickhandling. I totally disagree with that. Not that necessarily think it's the opposite, I just think it's what you naturally do better or what you've practiced more. I was a superior stickhandler, I scored a lot of goals, but not because I was a sniper with a great shot. I don't think one way is better than the other, I think it's just what you are used to and if you've never played a sport in your life and pick up a hockey stick for the first time, I don't think you'd be comfortable either way.....just pick one and get used to it....maybe give both a try for short period.
