"Why is my tenacious smoother then para 2"
You just happened to get one that is. Its not model dependent.
You could order the same two again and it could be the opposite.
I've had many Para's, and some have been super smooth, some in the middle, and a couple I had to send back. This could happen with any model, and variances will happen with any production company.
The only way to avoid it is to go Custom, or mid tech, and even with some of those there will be variances on the same model knife.
