I looked quite seriously at those & other programs, asking fellow Musicians & Educators for their opinions & experiences. Finale & Sibelius were the only ones which have all the "bells & whistles" which I would need, and still fell short in some areas of scoring. I would still have to go through all the charts & add this & that, correct things, & such.
   A friend challenged me to a "duel" where we both scored the same chart (one we both knew quite well), he using Sibelius, me my hand, trusty pen & staff paper. He lost.
I no longer work teaching for an institution, so I certainly can't get any discounts. When I looked at the prices & the cost year after year, I decided that as long as my brain & hand could still function, I don't need the fancy programs.
