Granted I'm not a unix admin guru, but my experience is that if you've got a unix that works reliably with little problems under your load stick to what you've got.
Each unix variant has its own little quirks that depending upon your users, and you, might be and issue.
For example, HP-UX has some quirkiness about how it handles busy disks and large file copies (where the file being copied is a substantial percentage, like 80-90% or more, of the FS buffer) all IO on the system stops. For busy disks you can get physical volume errors where disks are going offline under extremely heavy load.
Solaris on the other hand handles these particular case easily with much less disruption to service and users.
