I was wondering, aside from aesthetics, do the aftermarket suspension kits make the ride smoother or rougher?

I'm interested in buying a kit that provides a smoother ride but also better performance on the winding roads I drive on.
Generally, for daily driving, the rap on Koni FSD's + BMW Performance springs is: Excellent, absorbant ride with much much better handling.

Hey....Ground Control [Koni Yellows] Street/School will give you a dazzling performance envelope and a smoother ride, Koni FSD's a yet more compliant ride & smaller envelope. Both much better than any stock config. Check your camber - Ground Control's package includes M3 rear lower camber arms for added goodness; other things not seen in other mfr's solutions.

Both match shock to spring, prerequisite to good result, which is why I mention Ground Control vs Yellows + random springs.

Combine w/HP Autowerks' M3 suspension parts for exquisiteness if you don't mind another $2k+. Those rear bushings really gotta go; M3 sways yield flat handling.

I have Wavetrac limited slip differential - huge improvement and highly recommended by everyone who tries 'em. Everything they say and then some....

Maybe $7k parts for total improvement. Do you recoil? Don't! You'll bless yourself every day for doing all....
