Re: A very cheeky question...
G'day Jarrad,
I won't try to cover everything you related, but I'll try to hit the highlights.
<big snip>
Finally, the kicker. I'm currently using Cakewalk Sonar LE as my audio software. It has some music notation functionality but it's frankly rubbish. In this version, for instance, the only way you can get an accidental is to place the note on the stave, right-click it, select Properties and manually change the pitch from a drop-down box! It's a similar process for dotted notes or notes tied across bar-lines.
However, I will be upgrading said software to Sonar Producer 6 (that's the kick-ass, top-end version of Cakewalk) in the near-ish future. There's d*mn-all information available about its music notation capabilities and I don't know if they're just as shocking or whether they're more comparable with dedicated packages like Noteworthy. Does anyone here know if the full version of Cakewalk has proper notation facilities and can produce proper printed music with lyrics and whatnot?
Can't comment on Cakewalk - I've never used it and don't, at this time, forsee myself needing to. I'm more interested in notation than MIDI performance though NWC makes a fine sequencer and the MIDI exports work quite well. They aren't perfect however. NWC is primarily a notation package.
In summary, the features I really want are:
1) Ease of use
2) The ability to write at least 5 staves (usually S, A, A, T, B)
3) The ability to selectively export some or all of the staves to MIDI; being able to dole out individually-"performed" parts to people in the group along with the printed music would be invaluable
4) The ability to have multiple verses of lyrics under the stave and/or at the end of the piece
- 1) Of all the notation products I've seen, NWC is far and away the easiest to learn and use - with no exceptions
- 2) You can manage LOTS more than 5 staves - there is a limit but I don't recall what it is - I don't think anyone has actually hit it! However, there is a limit to the number of MIDI channels you can use. 16 per synth, and one of those (channel 10 on each synth) is reserved for drums.
- 3) Muting different parts is simple. Exporting the remaining parts does exactly what you're asking. In addition, with the Viewer, you can share copies of the .NWC file and the recipients can play it back in the viewer and see the lyrics along with their music (with a moving highlight or "chase") - will probably be better than a MIDI
- Up to 8 verses per staff. With creative layering, as many as you want... Unfortunately, you cannot have the subsequent verses at the bottom of the page without some kind of "post processing". Again, not hard just another step.
The features I'd *like* are:
1) Guitar chords
2) The ability to scan in sheet music
3) The ability to write out in MusicXML
- 1) Entered as text items - no problems. But being text items, they will not *transpose with your music
- 2) If you register for the NWC2 beta there are tools available to import MusicXML files. So, scan with SharpeEye, correct scan errors, export to mxml and import into NWC2 - works quite well
- 3) Again, there is a tool available for NWC2 files that will export to mxml
* This is not strictly true. NWC2 has a "user tool" facility for which there is a tool specifically designed for text chord transposition. There are also several other techniques that can be applied but I think this is the easiest.
I have also released some font suites that include a "Chord" symbol font specifically to make it easier to generate chord symbols. I "borrowed" the idea from some fonts that are available for other notation packages. Imitation is the sincerest form of flattery 
In addition RobertA has created a font called "FretQuik" that allows you to draw fingering charts/guides as text.

I absolutely do not want to have to use more than one notation package for the listed purposes, as I'm never going to find the time to learn more than one.

As I said earlier, I think NWC is far and away the easiest to learn and use. It is very keyboard oriented which makes it very fast, but if you must, you can also use the mouse for everything. Few people bother with the mouse very much.
I think I've covered most of what you wanted. If I've missed anything I'm sure others will step into the breach.
