Gran Turismo Series has a much larger and loyal fan base and has been around much longer than Forza Series.
Forza is considered an imitation of Gran Turismo series. Imitations are never as good as the Real McCoy in regards to popularity, brand recognition.
On XBox Forza also has to contend with Project Gotham Racing and other racing simulator game series.
On Sony console Gran Turismo is the main racing simulation series.
