You're comparing two different categories of SUV's.
Honda Pilot is in the same cat as Ford Explorer.
A Toyota Highlander is a small SUV like the Ford Escape.
I have a Honda Element (also a small SUV) and I used to have a Ford Escape. I LOVE my Element, it's so roomy (but yet so compact and easy to park) but it only seats 4. I loved my Escape but the back seat was cramped, but my kids didn't care lol.
My IL's have a Highlander and LOVE it too!! My SIL has a Pilot and it's a beautiful car but $$$!! (plus the gas)
