Cream or ointment?

I currently use Triamcinolone cream & tacrolimus ointment. Is there any difference noted between the triam cream vs. triam ointment? Years ago I took care of a lady (I was a home health nurse) who was riddled with PsO. She had both cream & ointment triam & she would have me put the cream on some places & ointment on the other. Then I’d wrap her in Saran Wrap. Anyway, I am curious if one was better than the other.
