I prefer Forza for the following reasons:
The career is more fun, not a dull as GT's feels to me
The AI racing in single player is better in Forza, far less tram lining
The customisation (mainly paint options)
The better community feel
Continual improvement on the series with each release innovating new features
The above are personal preference and not facts so nobody needs to get their knickers in a twist. In my opinion going forward, the number of fans is so heavily biased in favour of GT for historic reasons, that it can only start swinging in Forza's favour if they keep releasing quality games. I doubt it would be "the" sim racer though unless PD released a turkey by accident (very unlikely).
