"Im bumping this cause now naruto does control the nine tails and its no longer speculation.
Well that's very nice, but if you look back at the animation of the Lee vs Gaara fights, Lee was portrayed to be incredibly fast, especially when he activated the 5 gates (although not to the same degree as Ichigo), but since he is fodder compared to later characters, the animation is redundant (meaning you cannot rely purely on the animation used).
It must be noted that this is also the fastest that Ichigo has ever moved at; his bones and muscles are damaged when he moves at this speed, hence why he never moves at this level again. Since he was fighting on par with Byakuya (who has recently been shown to be powerful enough to cause significant damage to Yammy without his bankai), and since it triples his speed, he is moving here at 3 times the speed of Byakuya (which has not been seen then).
In terms of strength, Naruto with the fox would definitely be stronger; he was tossing giant rhinos around in his normal sage form. In terms of power, Ichigo is also outclassed; if Naruto can cause huge craters in his 4-tailed form, imagine the destruction he would be capable of in his 9-tailed state. We should also consider the resistance ot damage Naruto has whilst in his Kyuubi state, as well as his healing factor.
Naruto with Kyuubi wins, without it, Ichigo stomps.
