Personally, people pronouncing H as haitch really grinds my gears as it’s incorrect according to the Oxford dictionary, but how do you pronounce it, why, and have you ever had an argument about it?

I was recently watching a YouTube video, and the commentator pronounced the letter 'H' as Haitch. I've always pronounced it as Aitch, so I would like to know how many people pronounce it differently, and if this is a regional thing, or what?
I'm from USA, grew up in AZ and NC, and pronounce it Aitch.
The Cambridge Online Survey of World Englishes has the question, "How do you pronounce the letter 'H'?"
Their current results:
aitch (85%)
haitch (12%)
I use something else (2%)
You can see a clearer (and navigable) image of this response map at the link above by registering and taking the survey:
According to the OALD, the standard way to pronounce the H is this one, which is without the "H" sound in its pronunciation.
Although on Wikipedia, it says there is also the other pronunciation (with the "H" sound at the beginning) which, anyway, is considered to be nonstandard.
