Both programs require work, effort, and excessive attention to detail to make a beautiful score. Switching to Finale will only illuminate an entirely different path of obstacles for you to navigate.
And in the end, you will be ultimately hindered by the lackluster default music fonts (of which I think Sibelius is slightly better here) which will give your music a generic, computerized look. Of course, even more time and effort can get you a better music font to use. Then there's all that time making a collision markup for the font....
Suffice it to say, if you want a score with the beauty of a Henle or Barenreiter edition, you will have to spend hundreds and hundreds and then more hundreds of dollars getting the basic materials, and then be prepared to spend dozens and dozens of hours working on a task that would perhaps be an insult to monotony.
All hope is lost. OR is it?
