Good discussion! I have owned a Toyota 4Runner and a Nissan Pathfinder and IMHO opinion there are many differences in the two. If you're looking at pure power and speed, the Pathfinder would get the nod. My wife and I loved our 4Runner and went to purchase another because we needed the 3rd row seat. We were all set to buy it until we saw the 3rd row seat. The 3rd row seat in the 4Runner hangs on the side of the roof and creates terrible blind spots and makes putting a stroller in the back near impossible. This was the ONLY reason that we purchased the Pathfinder.
The 4Runner is more refined, has a better build, and is more comfortable than the pathfinder. Not to mention that the engine is much quieter than the Pathfinder's is. Kids can actually reach the outside door handles on the 4Runner... don't even get me started on the outside door handles on the Pathfinder.
The interior in the 4Runner looks posh while the interior of the Pathfinder is quite bland without a lot of creativity put into it. As far as looks go, that is a matter of opinion, but both the wife and I preferred the 4Runner by a mile. I wish that Nissan would have had an interior design somewhere between the 4Runner & Highlander because those are both pretty cool designs.
When we traded away our 06 Pathfinder last week for the Armada, neither one of us shed a tear. That was not the case when we sold our 2000 4Runner! Don't get me wrong, the Pathfinder is a capable vehicle and had very few problems in the two years that we owned it. The Pathfinder was just a bland vehicle that you really never got excited about driving. It wasn't ugly, but it wasn't beautiful either. It was indeed one of the most uncomfortable vehicles that I've ever set in. It doesn't even compare in comfort to my Titan or the New Armada. We could never have taken it on a long drive or vacation. When we did... we always drove the Titan, which is a dream to drive long distances in, aside from the gas mileage which I found decent in a truck with type of power.
Quite frankly, I would not own another Pathfinder. But, if you're on a budget and need a mid-size SUV with a capable 3rd seat... it is OK. However, their are better choices IMHO, and if we would have had it to do over again, we would have purchased the Toyota Highlander. Hopefully, the Nissan Murano will one day compete with the Highlander and have an optional 3rd row seat!?
