My experience with spectrum display actually exceeds
both of yours (if such a statement makes any
grammatical sense). I've come to the point where I
feel like I have tunnel vision when having to depend
on a simple digital display for telling me where I am
in the band. Not to mention the total lack of
awareness of what is happening up and down the band
without having that spectrum display telling me
visually.

I find with N4PY software running in dual Pegasus mode
that I can find some surprisingly weak signals on a
band where the background noise is quite low such as
with 2M weak signal work.

With N4PY software running in dual Pegasus mode you
have more or less the same thing, but with a mouse
click or two you can have 2 separate RX's as well.

Not at all, it took me all of 30 seconds to figure out
that it is the cat's meow for quickly determining the
presence of signals across a band or its general
propagation condition overall.

Yupp, and I've gotten to the point where I won't even
go into a VHF contest anymore without it up and
running on 6&2M.

My main reservation about the spectrum display being
on the radio itself is that they are always too small.
To really gain a true appreciation for what it can do
for you; it really needs to be on a nice big computer
monitor.
