Well if you could see yourself driving it stock, then go with the PRO. I hear you can get the pro with dual zone air condition so that would be a plus for a spouse.

I just didn't like the poor ground clearance of the 4Runners in general (mine was 8" at the front skid and the Pro I hear is 9.0, Toyota lies about it being 9.5) so I went with the TRDORP and put a lift on it. My "3 inch lift" gave me 4" additional at the skid so now I have 12.5", the 1/2 for the bigger size tires. For a stock 4Runner, you may want to invest in more skids though since the ground clearance is poor unless you only drive on mild 4x4 roads. I also get a bit more articulation than a Pro because of my KDSS so that was a factor in my purchase decision.

And if you want a cheap but doable lift, I think you can get a Bilstein setup at about 2.5" front and 1.5"back for less than $1500 if you don't upgrade your UCA's. That's installed. That's what a buddy of mine did and that included installation. Then if you had the TRD Pro wheel and tire option ($1700 option but negotiable as anything else is) on the TRDORP you wouldn't even need to swap wheels. You could drive the Nitto's that come with it and then replace with 275/75R17 when they wear out.
