Less sidewall of tire = slightly firmer ride.
Generally, I like the adjustability of koni style struts or coilovers.
Springs, will not have any adjustability, therefore, you get what you get. Best is to have the rate match the valving if you go that route.

For example, my Nismo is great on most road surfaces, however, with non-adjustable spring rates, rebound, etc. I'm stuck, so on very rough surfaces, it's very bouncey...
