Before either truck adds aftermarket gear/accessories there's a 2300-2500lb difference, which is nothing to sneeze at. That said, the PW makes almost 150 more HP, 165 more torque, it can tow anywhere from 1.5-2x's as much, has full-size straight axles front and rear, comes on 33's and can fit up to 37's without a lift, has both front and rear electronic lockers, an electronic disconnecting front sway bar, a 12,000lb Warn winch, and carries 33% more fuel. This is all before you add a single aftermarket part to it. When compared to a TRD Pro it can be had for the same money new.
So yea, it weighs more, but as you can see, you get a lot more for your money and it would be nearly impossible to match those specs on a Tacoma let alone for even remotely close to the same amount of money. Beyond all of that, the biggest difference is the size and storage capabilities between the two. The Tacoma has a nearly unusable rear seat for anyone larger than 5'6" and a 1.5' shorter bed. Now don't get me wrong here, I love the Tacoma, I had a TRD OR for a while and it was a good truck, but these trucks just aren't comparable in any way. It boils down to whether or not the Tacoma works for you or not. If tight spaces and trails are key and you travel with only one other adult or small kids then the Tacoma is a very viable option.
