That's certainly not true; many stations up there in C-land have as
much or more power.

It does have the largest *land* coverage area. Some of the Mount
Wilson FMs have larger coverage radii, but cover more ocean. (KPFK in
particular is usually cited as number one among these.) Here's the
complete list of licensed facilities in the U.S. with more than 1000 m
HAAT and more than 20 kW ERP:

Notice that there are only two "W" callsigns in this list, and both of
them are on Mount Washington. Note also that WHOM operates with an
ERP approximately twice that of the all the other stations. (As a
point of trivia, KCBS-FM's "standard" predicted 60 dBu contour
includes all of L.A. county; KPFK's does not. KCBS-FM certainly has
the largest coverage by population served.
Just by way of contrast, here are all the "superpower" FMs (those with
more than 100 kW ERP for class Cs, or more than 50 kW ERP for class
Bs, regardless of HAAT):

What's notable is that so few of them were built with any height at
all; there used to be more, but over the years stations have found the
call of additional HAAT to be more compelling than the "superpower"
designation.
