Good GM Soundfont Vote

I am looking for a General Midi compatible (128 instruments + drum kit) decent quality soundfont file "sf2".  Originally I asked for someone to help make VST instruments, however I realize VST instruments might be tough to make.  But what I can do is implement a good soundfont that I can distribute with our music notation program.

Here are some candidates, and I will contact the owner of these soundfonts once we come to a general consensus on which soundfont might be best:

• Princess Soft SF2
• Compifont
• Papelmedia
• Ntonyx
• Pro Vitamin

What do you guys think?  Are there any other candidates?

OPL3!

... jk lol. Those look pretty good.

I had to look that one up, but I could put in some retro sounds, that might be neat!  I've been demoing some soundfonts, and none of them seem that great for orchestra works.  I think what I may end up doing is shipping the product with one of the above soundfonts, or multiple depending on the size of the soundfont (with the permission of the creator).  But I think VST is the way to go, and I am going to look into integrating VST support with the product.  The only thing I can't do is ship with VST sounds since I won't have the rights, and MakeMusic bought Garritan, so Personal Orchestra is out of the question!

I downloaded two from your list, Compifont and Ntonyx and tried string instruments and piano on Fluidsynth. I personally prefer Arachno and Timbres of Heaven over both of them.
