Current LTS versions of Debian and Ubuntu come with some version of
Py3, and some version of Py2.7. You can see the exact 3.x versions
here:

https://packages.debian.org/search?keywords=python3&searchon=names&suite=all&section=all&exact=1
https://packages.ubuntu.com/search?keywords=python3&searchon=names&exact=1&suite=all&section=all

I don't know how to check RHEL package lists without having a license,
but RHEL 4 and 5 came out before Py3 was released. So "we need to
support RHEL 4" would be a legit reason to avoid Python 3 - but it's
also a reason to avoid Python 2.7, as RHEL 4 ships with Python 2.3 or
2.4 or something. Also, I believe there are backports available,
though I don't have proof of that.

Use Python 3.
