The latter.  Strictly the latter.

Tell that to an FT-817 with only the stock SSB filter.  (Yuck!)

That's exactly what I mean, and I am referring to both SSB and CW.  I
consider a narrow SSB filter to be the best QRM fighting tool on SSB and
a 250Hz or narrower filter to be a must for me on CW.  Narrower is
better provided it doesn't ring or become impossibly hollow sounding.
