No wheel wells in the Ridgeline bed. The bed is also wider than the taco. You can lay full sheets of plywood, etc flat in the bed.
Taco bed is deeper. So, if you have a cover on it, you can fit taller things under the cover than you can in the Ridgeline.
So, it's all in what you want.
Ridgeline also has the awesome trunk in the bed. Very useful. But, not as useful if you are going to have stuff loaded on top of it so you can't open it.
You just need to get whichever one suits your needs better.
I would argue that the Ridgeline can haul more. I know that you (op) think that the taco can haul more. Maybe you mean the tow rating? Ridgeline has a lower tow rating. But it tows very capably.
Taco has better ground clearance. Which is good if you ever go off road. But it's also good if you are ever in really deep snow.
They feel very different when you drive them. Many people will have a definite preference one way or the other in that regard.
ETA: all of my comments are based on 2017 model. There may have been changes made since then
