If I were to buy my Sport again, I would probably get the V8. However, in my region, the V8's are hard to come by in the trim I wanted (mostly Limiteds with the V8 everywhere I looked). I wasn't about to special order it either since I'm an impatient b@stard. On the other hand, I love my v6's. I know it's a small point in its favor but I love the top mounted filter location and the timing chain. A little louder than the V8, but I didn't buy the 4runner expecting a quiet engine. But I do envy the fact that the V8 is full time 4wd and you don't have to give it a second thought (plus it comes with a tranny cooler standard, big +). I know you can run the v6 in 4wd all the time but sometimes it's also fun to run it in 2wd. Btw, I do tow once in a great while but nothing over 4k lbs. Like others have said, you test drive both and see whichever floats your boat.
