I was just checking out the Demo's of Finale's Allegro (one step below "Finale"-the top of the line software--about $199) and "Sibelius First" (One step below Sibelius 5--about $129.00). I thought that Sibelius First has a great interface, but was lacking in 1 or 2 things. I did not like how Sibelius First notated drums. You do not have instant notating access to all the drum sounds on the staff. You can put drum note down on the staff, but to get a cymbal sound (which are above the staff) you have to use your computer keyboard to scroll through the different drum note heads until you get the right sound. You will hear nothing if you put a note above the staff without changing it to drum notation after you plant a note. It's weird and inconvenient. Allegro you just move your cursor up and down the staff until you hear the correct percussion sound that you want--Allegro automatically changes notation. Finale Allegro gives you way more customizations, too. Sibelius 5 had better undo's. You can see a list of actions and undo them all. Allegro you only have 1 undo. Another nice thing about Allegro was that it plays back chord symbols. Sibelius First does not.
