Ok... Not a small job ;-)
For config files where it's exactly the same on all machines, that's
super easy. It's just stored once on the Puppet Master and file is
managed on all Puppet Agents.
I'm not sure if rdist has some templating system in it for machine
specific config files, but Puppet has a Ruby based templating system
that can handle lots of cases. Other more complex files can be done with
what are called "Concat" files - one file is assembled from different
fragments.
Scripts and especially compile binaries are tricky. Puppet's not the
best File Server. The more files you manage as actual Puppet Files the
more work is involved. By default the Puppet Master MD5 sums files and
the Agent does the same to work out whether a file needs to be copied
down. There are some improvements you can make, like changing the
checksum method, but 260MiB to every 200 servers? Sounds like a bad idea
before you start.
What problem are you trying to solve that you think you need Puppet? The
recommended Puppet way would be to package your binaries and use Puppet
to enforce new versions of the package. You said your Admins are used to
just getting on the rdist master, make changes and then practically an
rsync? If that's the way you work and the way you want to continue to
work then I don't think Puppet's going to beat rdist for this use case.

5800 files go out,(or more specifically, get synced) identically, to
all machines, every night.
Probably 200 of those are config files. the rest are specially
compiled binaries and util scripts.
