I don't think we're really disagreeing, just probably coming at this
from different backgrounds.
My point was merely to not assume these days that Mac's are closer to
ColorMatch and PC's closer to sRGB. That may have been true 10 years
ago, but today the distinction doesn't apply generally. I'm sure
there are exceptions.
In my experience, sRGB is closer to what most people use without ICC
savvy, either their own or their applications' (and most people can't
afford Artisans). Although none of us wants to have sRGB imposed as a
standard, as some industrial giants would like, my experience says
that it is often close on both PC and Mac systems. Hence the de facto
comment: this merely reflects experience, not law. I can't speak to
high-end equipment like Artisans, which certainly gives users more
options than usual.

Although Andrew (Rodney)'s advice is excellent as usual, I wish to
point out that my Mac monitor is calibrated to 6500K and gamma=2.2,
which is closer to sRGB (or a PC monitor, if you wish) than
ColorMatch.
There's no reason why a Working Space gamma and a display gamma have to
match or even be close. There are slight advantages to a 2.2 gamma in a
Working Space.
I don't calibrate my Artisan to 1.8 or 2.2 (I'm on a Mac). I have it set to
it's own, unique native gamma (there's a way to do this on the Artisan). The
artisan can the set to the natural TRC and records it to the ICC profile -
leaving the DAC LUT linear.
Outside an ICC savvy application there might be reasons why you'd want a 2.2
gamma and a 2.2 Working Space but in such a situation, the preview is such
that anything is possible (your mileage may vary).
I still see this type of (Mac vs PC) advice, but mostly in PC-centric
sw and hw. I'm surprised to see Andrew Rodney make this comment,
knowing that he is quite familiar with Macs.
I'm talking about an untagged file or a file outside of a color managed
application. Assuming the person wasn't intelligent to place a tag in the
file, we have to simply guess. I'd start this guessing game picking
something like ColorMatch if I knew the user was on a Mac but if that didn't
appear correct, I'd try sRGB. After exhausting all possible "common" Working
Spaces, if the file still looks ugly you really do have RGB mystery meat.
sRGB seems to be a type of de facto standard out there.
I really hope that's not the case!
