not much different.
The usual crop of languages and libraries
(C/C++,Fortran,Pascal) on both sides.
Ultrix even had a PL/I compiler,
I don't know if OSF/1 had one right from the start.
The main difference I can remember that
mmap() was sort of substandard on Ultrix
and OSF/1 supported dynamic loading.
Not much progress, considering the relevant time span
from 1989 to 1992/93.

Installation procedures are almost undistinguishable
(did it many times).
Neither Ultrix nor OSF/1 in its first versions had
admin tools to speak of.
At least nothing comparable to HP's contemporary SAM,
let alone IBM's smit.

Last business report (and several ones before)
says Power systems increased business,
and istr Oracle claiming the same for their
inherited Sun gear. HP BCS may be on the decline,
but that's due to their Itanic desaster.
Not inevitable fate, but self-inflicted damage.

If you refer to VMS: it's in a much worse shape
if you consider that HP says the vast majority
of Itanics sail under HP-UX.
