GameInformer, Matthew Kato - "Two games are at the starting line, set to race off into the open frontier. We take a look at Criterion's Need for Speed Most Wanted and Playground Games' Forza Horizon and size up these two contenders.
Back in 2010, two racing games, Black Rock Studio's Split/Second and Bizarre Creations' Blur, went head-to-head on store shelves. Although the titles weren't completely similar, they defined the racing genre at the moment. This October, Forza Horizon (above) and Need for Speed Most Wanted will go up against each other and present their own visions of open-world racing.
Coming off of E3, where I got a chance to see and get some hands-on time with both games, I thought it would be useful to compare them in a few key categories. Of course, a lot of development time remains before October and I don't know every detail about either title, but this might give you a better look at both and help you determine if one is more up your alley."

Former Playground Games veterans Gavin Raeburn, Jon Davis-Hunt and Marco Conti reflect on Forza Horizon’s origins and how it “beat every other driving franchise out there.”

A replica of Most Wanted’s famed M3 GTR is on display at the BMW Welt exhibition until 6th January.
for me its easily NFS since its my 2nd favorite racing series behind GT. i wish PGR was still around as this was my favorite racing series on xbox/360
Criterion beats everything
Out of the two, I'm going with need for speed, despite not having the choice, but even if I did, it's dat fun factor.
Hmm, I see a trend in the comments so far, instant vote against a 360 exclusive.
I'll be getting Horizon on day one , it looks like the game TDU2 should have been.
