To me, the answer lies in determining what you take with you on adventures -- both people and gear. 4Runner is better at keeping all your gear enclosed and dry, which also means less prone to theft. The Taco is better at segregating your gear and leaving the passenger compartment for, well, passengers; no worries about muddy and wet stuff inside. Having dogs, kids, people going with you will influence your choice. For example, it's going to be hard to take a dog or two and a few friends at the same time in the Taco, while the Runner will take care of that with ease. The 4Runner is better as an alternative shelter to sleep inside if the weather is really nasty and you have to get out of the tent. Tacoma might have longer wheelbase (I don't know for sure), which can make it for a more comfy drive on the roads (more stable) but has disadvantages with breakover angle offroad.
