I don’t have a copy of Finale, but it works in the same way as Musescore and so will require you to do a lot more editing to get acceptable output. Here are some sample images:
First typeset with Finale
Then the same music imported into Denemo using MusicXML and typeset with LilyPond (no manual adjustments of the music, no tweaking!)
There are distinct stylistic differences here. The vertical lines in Finale are lighter for example.
The bottom line, however, is that if you want to alter individual note spacing, re-shape most slurs, re-position dynamics and so on, then a drawing-program approach such as Finale could be good for you. But if you are happy to let LilyPond look after the music typesetting then go with Denemo.
With Denemo you can tell LilyPond generally how you want your score to look – more spaced out, more tightly packed – you can set your style and then forget about adjusting things for each score.
You can also graphically re-shape slurs and re-position ornaments etc using Denemo, but that is just for the occasional case. If LilyPond’s typesetting is not what you are looking for and you need to tweak much of the music then LilyPond’s typesetting is not for you.
The Reunion Example
Arne Peters kindly imported the musicXML file for Reunion into Finale 2012 and without tweaking it generated the following typeset:
Once again, as far as musicXML import is concerned, it is quite a good job (the octava marking is missing. But a considerable amount of hand positioning is required to typeset this properly which contrasts markedly with the typesetting that Denemo offers even before any tweaking is done:
The Adon Example
Arne has also imported the Adon example used in the MuseScore comparison into Finale 2012:
The underlay of the lyrics here is not perfect with collisions and near collisions with the barlines as they cut through the lyrics line. Compare this with the Denemo version:
