I noticed a mail server I recently became the admin of has both
SMTPS and Submission running for users to send mai through. As far as
I can tell the two do basically the same thing. On that assumption, I
would like to apply the KISS rule and use just one or the other. Which
is one is best is for users to send email?

Presumably you mean port 465 (SMTP immediately over SSL) and port 587
submission that allows the negotiation of a TLS session and is a
slightly different protocol than SMTP.

The registered port using a well-specified protocol (i.e. mail
submission on port 587) is a better approach. If you can turn off the
decade-obsolete port 465 service, you should try to do so.
