I'm weighing in on this, too, because it was a major decision for our family. We ended up getting leather, and I am SO happy that I did.
I love it! It is so easy to clean -- and you can see in a second exactly where that sticky mark is and whisk it off with a damp paper towel. The cloth interiors in our last two cars did hide dirt to a degree, but, wow, when you looked more closely, it was filthy. Imagine a yogurt smoothie spilled on the backseat and not discovered until the next day? In the leather, I could have simply wiped it up...in the cloth, the smell was in there for good.
A Hershey chocolate bar melted into the cloth ... forever. A piece of Laffy Taffy ... forever just a touch sticky.
And then there's my friend whose 4-year-old threw up -- twice -- within the first week she had her new leather interior. No problem, she said, it was wiped up and out and she didn't cringe at the thought of anyone sitting there again.
Heat was a concern for us, but I have to tell you that it has not been a problem at all. And we do live in the South, and it is humid and sticky outside, but the leather feels smooth and good to these bare legs -- not fuzzy and itchy. My sister told me that the leather seats in her car without tinted glass do get hot, but her van with tinted windows really keeps out the heat. I guess my EX-L is working the same way, because neither child has ever complained of the seats feeling hot -- even after sitting in the parking lot in 96 degree weather at the pool! Any my kids are complainers, so I know they'd let me know...
I also read the posts about fuzz coming thru the perforation holes in the MDX, and saw it myself in a used one on the lot. I now have 3,000 miles on my Pilot, and after nearly 6 weeks, see no sign of fuzz anywhere. The holes are also too small to catch crumbs (tho I personally would have preferred hole-less leather for a family vehicle).
The leather does seem a little thin compared to some other cars, so time will tell how it wears and holds up. But for the moment, I absolutely LOVE it and am 100% pleased that I opted for it rather than cloth. I will never want another car with cloth!
My two cents...
