Surely there must be some significant differences? It's hard to believe they are all the same. Claiming they are all the same is a strategy of propagandists (I'm not saying you are one; I'm saying it's a dubious approach). 'It's all the same' is the opposite of truth and accuracy, which require discernment; it the justification of liars (again, not the parent).

Anyway, the parent's claim isn't my experience, but now we're just one person on the Internet disagreeing with another.

I'm not saying their all the same. I'm saying Wikipedia is generally better (though of course far from perfect), without trying to make difficult-to-quantify claims about how much better.
