I have both emulators i used to prefer No$Gba because of the speed factor, but in pokémon games the 3D isn't supported correctly. HG & SS crashes every hour, and you can't play ANY NEW pokémon roms whitout Action Replay Codes to pass Nintendo security!!!! In the beginning Desmume did not work in my PC but since the 0.96 version it allowed me to play ALL DS games!!!! So for desmume win (maybe it's slower than No$Gba but it do not crash and i don't need to beg someone for giving me the AR codes to play Black & White. (Yeah using No$Gba Zoomer allow you to have a larger screen but the framerate is also slow in other games like Castlevania (Alls DS Castlevania) it is simply unplayable!!!!!!
