Stock vs stock on what? This is stupid... Are we talking sand, dirt, uphill, downhill or concrete WTF?
The only way a 700XX would beat a 700 raptor (Both stock) would be down a steep hill were the EXTRA 90 LBS would come in on the XX... So if you ride downhill all the time hmm might be a good choice..
Like my grandpa always said... "When I was a kid we walked to school uphill in 4 foot of snow both ways" Thats BS And we all know that we don't ride downhill all the time.
