What are your priorities other than reliability?
At some point Nissan should sort out the transmission in the QX60. The question is when this happens.
Among upscale three-row crossovers, I really like the Acura MDX. The first-year 2014 hasn't been doing well in our reliability survey, but there's a good chance (based on past history) that the 2015 will be better.
The Highlander is a good all-around crossover. Its main weakness is a tight third row and limited cargo room behind the third row. Its main strength is reliability.
The Hyundai Santa Fe has especially car-like handling. It feels compact and agile compared to the Highlander, yet has more third-row legroom. Reliability wasn't good with the first model year, the 2013, but the 2014 has been much better, and the 2015 should be at least as good as the 2014.
The Dodge Durango is a traditional SUV, but its strengths include seating, ride, and handling. The 2014's reliability has been so-so at best, but as with the Acura the 2015 should be better, if not great.
Ford offers two you didn't mention, the Explorer and Flex. Seat comfort, ride smoothness, and space behind the third row are strengths of both. The Flex is longer and lower, and its styling is polarizing. Both are a little hard to see out of because of thick pillars.
