If we have an 18x9 weighing 19lbs and a 17x7.5 weighing 22lbs, will you notice the power difference? and which one will have a better response?

I think Tenuki sort of responds to this, but the answer is in where the weight is. I think a large portion of the weight of the wheel is in the rim - the farther you put weight from the hub the more power/torque required to accelerate it (like a spinning figure skater - arms out slow, arms in fast). So likely the 17" would have the mass closer to the center. The corresponding weights of the two tires would also come into play.
