Actually, I've never thought Collins SSB sounded all that terribly good.
The KWS-1 has a bit wider transmit filter than the other usual suspects, but
in general, the transmit bandwidth is too narrow. There are important audio
queues in both the low end and high end (up to 4Khz or so) speech spectrum
that are completely missing. This isn't just a Collins problem -- I'm not
singling them out to pick on. And the typical receiver, with it's shiny 2.1
Khz mechanical filter or equivalent, chops those important queues out even
if they were being transmitted.
I am not a proponent (nor opponent, either) of high fi SSB, but you don't
have to go too far beyond what is the politically correct norm to get a
signal that can actually be well understood (per Bacon's point).
And of course there are other factors -- tuning errors, distortion products,
a heavy hand on the "processing" control, what-have-you. AM signals can be
mushy and hard to understand, too.

The KWS-1 has issues in that it transmits ONLY one sideband NOT both.
That is precisely WHY I passed by the one that was/is <eventually>
available WITH the matching receiver. Both are completely restored.
As such - it is a POOR example to cite for "AM vs SSB"
