SNES had 3 background layers and color math/transparency, TurboGrafx 16 was stuck with one background layer. SNES also had much better sound capabilities.
I'd say TurboGrafx's biggest advantage was that they had a full handheld version of the system available very early on. The Turbo Express crushed the Game Gear and Lynx in terms of power. (The Game Boy still beat all its more-powerful competitors because of its far lower battery consumption)
I'd say the Game Boy also won in terms of library of games, and the popular properties owned by Nintendo, such as Super Mario Bros., Metroid, The Legend of Zelda, among many others.
Yes but that was due to it's popularity, not the cause of it, there is quite a bit of network effect, but that only comes into play once you have the network.
The gameboy won because it was half the cost of any of it's competitors. while being more than half as good.
