In addition to the below, there is no real assurance that the baking
soda that is sold as being better than Arm and Hammer is not made by
Church and Dwight. It makes sense to me that ALL U.S. produced baking
soda is refined by Church and Dwight, because I live where it is
mined and produced, and all the Trona mines here sell soda ash to
Church and Dwight. Church and Dwight does not mine their own soda ash
(the raw ore is called Trona).
There is also soda ash produced by chemical processes, that is not
mined. So far as I know to date, the only natural deposits of Trona
are the one here in Wyoming, which I believe is the only commercially
viable site. There are Trona deposits in China also but last I heard
they are not being developed yet, also the method of making soda ash
chemically uses salt, and carbon dioxide or monoxide from coal and a
LOT of energy to make it. Still it is now cheaper in Europe and China
to produce it from the solvay process than to ship in mined soda ash,
because of shipping costs. At least that is my current understanding.
Trona mines are very deep, and costs to develop mining are probably
now prohibitive.
Since there is plenty of soda ash produced in the U.S. in Wyoming,
and it would very likely be prohibitively expensive to ship in solvay
process soda ash or refined baking soda from either Europe or China,
it is probably the case that ALL the baking soda in the U.S. is mined
here and refined by Church and Dwight. If the source of the more
expensive supposedly more pure baking soda is solvay process soda ash
from Europe (could as easily be from China), then I still don't see
any advantage to buying it, because there is really no guarantee it
is any purer. But there are always people who will believe any kind
of marketing hype, and will always think it something costs more that
proves it is better.

Out of curiosity, I looked up a site that explained the various
methods of producing baking soda. None of them involve
aluminum. For this reason, I am comfortable with any brand of
baking soda as long as it is not made in China. I would then be
concerned about lead, melamine, or other odd contaminants.

Am I missing anything?
Why would one choose to disbelieve one maker, yet believe
another? Don't they all have the same interests? That is,
producing a product for which they can sell at a profit? Making
sure the product is what they say it is so that they maintain their reputation?
Now, baking soda is sometimes confused with baking powder, a totally
different product. Some baking sodas are made with aluminum
salts. Is this causing some confusion with baking powder?
