I never liked 50 or 55 mm lenses for portrait even on FF. I liked 90-105. On APS-c my 70 ƒ2.8 macro rocks, and I'd love a 77 ƒ1.8 ltd. Just from my experience, there are a large number of portrait artists who prefer long focal lengths. I'm not sure if it's the majority of them... someone would have to do some research, but it is a healthy number.
The ƒ4 of the DA*60-250 makes it less desirable for portrait work. But then, I just don't do a lot of portraits. I was trained for it, but, it's never interested me. If portraits are the thing, sell the 60-250, get a 77 ltd. You've already got a 55 if you decide you like something in the 50's better.
