I like Driveclub because it doesn't restrict you to a single place like an open world game and instead takes to you a ton of unique places like Chile, India, Canda, etc. It's also the most gorgeous racer of the three.
I like Forza Horizon 2 because it takes the realistic simulation handling of Forza along with it's incredible car catalog and applies it to a beautiful European landscape with awesome car challenges and one of the best music soundtracks in existence.
I like The Crew because it spans the ENTIRE FREAKIN US from huge spanning metropolitan cities to snow capped mountains and really makes you feel like you're on a classic American road trip.
I love them all.
