Inland North (description posted above).
Which is a bit whimsical since apart from seven years in western Montana — 35 years ago — my entire 59 years has been spent in the SoW.
And I tend to say “soda,” too.
The inland north, which is funny considering I’ve never been there. I’ve lived on the West coast all of my life (so far). And 37 years of that has been in Alaska (I’m almost 48), we don’t have much, if any, accent at all.
There were more than a few questions where I was thinking “none of the above”, but chose from what was available. Normally, for soft drinks we say “cokes”.
Well, bless your heart!
Howdy! 
Inland North, and I’m from Buffalo. I used to say pop, but when I went to boarding school all the girls from NYC and New England made fun of me. Now I say soda.
Midland accent.
Raised in Arkansas, but moved to southern Illinois, so sounds right to me.
Another quiz on the site sez I’m 100% true Arkansan, though. I’m so conflicted!
That’s Texan for “you’re a big poopy-head but I’m too polite to come right out and say that” isn’t it?
Yup, they got me: Inland North.
Since I relocated back here from NYC, I still catch myself pronouncing Mary/marry/merry differently, but I now say “pop” instead of “soda.”
Yes I’m from the West. But I don’t have an accent! I guess my “dudes” and “hellas” will distinguish me as a norcal chick. 
Having been raised in Texas, I feel qualified to admit and agree that a Texas accent is indeed rather annoying.
I got the same accent only I was born on the big island of Hawaii. I do have a bit of pidgin though.
Another Midland accent here.
I was born in North Carolina, moved to Germany when I was 7, moved to Washington when I was 12 and been here the past 10 years. Sometimes my NC accent comes creeping out.
I got “The West” which isn’t right. I grew up near Washington DC and I speak perfect broadcast English though I occasionally use some some Southern expressions such as “Howdy” for color. I’ve traveled out West all of about 4 months in my life and I don’t think I picked up anything.
Apparently what makes the difference is that Midland types pronounce “stalk” and “stock,” and “collar” and “caller” differently. I’m honestly not sure if there’s any slight difference in my own speech.
The west, and I speak surfer too, dude. Although I think I’ve got the regional variation of valleyspeak.
I grew up in southern Ohio, so they got that right. But what’s this nonsense about not having an accent? (When will that myth die?)
The Midland. Which even though I was born and raised here I would say is accurate. People say I don’t have an accent at all.
Yup, New York City now, raised on Long Island. I pronounce all the words asked about in the test differently.
All together now…
“NEW YORK, NEW SOUTH WALES, IT’S A WONDERFUL TOWN…”
(like Cunctator, I tried it for fun)
And my overriding memory of that quiz is that whenever the question asked “Sounds the same or different?” my answer was invariably “different”. Where there were three words, I always picked “all three sound different”. I don’t know what that says about US regional accents.
I don’t think that’s the answer that clinched it for Philly. I answered the same as you on that question and it said I’m from the West.
Aussie # 4, also with the northeast.
NONE of those words sound alike, they all sound different!
