You have to understand that any orbital rocket is heavily optimised. Adding
any non propulsive/payload mass to a rocket reduces the payload compared to
the maximum payload you could have had if you hadn't had to add it; for
example, you could have added fuel and tankage instead, reoptimised
everything, and ended up with more payload.

Uh, dry mass on a first stage <> payload to orbit mass hit. That's kind of
the point of staging. Did I misunderstand that?

Bear in mind that "sophistication" actually means unnecessary complexity.
The word derives from "sophistry." A sophisticated argument is one that's
excessively complex, hard to follow, and deceptive.
I'm sure that is not what you meant, but your accidental use of this
(frequently misused) term underscores an important point: complexity, in
itself, it is not a virtue. Complexity does not equal utility, or
importance. The design of a mission, or a piece of hardware, is not better
simply because it is more complex. A design should be as complex as it
needs
to be to accomplish its goals, and no more so.
I have no idea whether the New Horizons mission is more complex than the
SpaceX mission. I don't even know how you would measure the two. I do know
that the comparison is irrelevant. Each of them is as complex as it needs
to
be; that's all that matters.

There can be sophistication in purpose of a spacecraft mission and
sophistication of the craft's hardware. I agree both types of
sophistication are not necessarily related.
