Let's stay on topic.
The OP wants a smoother OEM like ride. Coilovers of any brand will not offer that level of comfort. Not to mention that if he upgraded to Koni Yellows and mated his ground controls to them, they would outperform the Teins for less than half the price, but that is a whole 'nother can of worms I do not wish to open.
Topend, it is a combination of the springs and shocks making the ride stiff. A stiffer spring requires a higher rebound setting on the shock to prevent it from bouncing all over the place. A softer spring will require a lower rebound setting, so the ride will be much more comfortable.
