i keep getting PM's with the same question

Most haven't owned both and prefer what they own or purchased

I am on the koni side.... Been using their stuff for many years in my SPG as well as in my viggen with aftermarket springs. Great stuff..... Rode in a few bilsteins equipped c900's but never a newer saab thus no comment

I have had both and my vote is with Koni yellow adjustables.

My first set was killed by a set of Intrax. Koni not only rebuilt them for free, but custom valved them to match the set of Eibachs I was going to use for no cost to me. Customer service FTW.

Koni's are adjustable for rebound. Bilsteins offer their benefits on the compression side. Both are good. I personally like the 'steins better. They are much cheaper, and much more substantial. Plus, they are aggressively valved for lowered cars. I have ridden in cars equipped with both; the Koni's on full soft are softer than the billy's, but that is about it. I really don't like the way the car feels with Koni's--to me, it feels like air suspension that has been pumped to "full hard", like you are riding around on over inflated dodge-balls. Other people say the billy's are made of granite--I respectfully disagree. The main problem is actually endemic to both makes; our suspension is so limited in terms of travel on a stock setup, that lowering it gives you ~1.5" before the bump-stops. This makes for a miserable experience when you slam a bump and it all goes into your strut towers with a calamitous "BANNNG". Lastly, my gripe with the Billy's is that they have this trick valving that makes them go soft upon impact with a howler, which exacerbates the aforementioned problem.
YMMV.
The question is whether or not you can be lead to believe the Koni's are worth the price difference.

Driven/owned both on OG 9-3s.

Konis ride better on a less than perfect pavement. Less busy, less jarring.

Both are impressive on pefect pavement.

I have Bilsteins on my Driver SPG, it rides well and I like them. I did not like the Bilsteins on the 9-3. I have a full set of Konis to try on my other SPG (too nice to DD) this summer.

Yeah, I need to install my bilsteins in the viggen to really have an apples to apples idea.

I had Koni "reds" on my track oriented SPG. They were terrible with whatever spring rates I was running. Went with the bilsteins and I could brake later and come into corners harder and faster. I liked them on the c900 way more than the Konis I had. Had both brands on my og9-3's too. I like the koni race and koni sports better than the bilsteins on that car. For a lot of reasons....

I've owned both, the adjust-ability of the konis is extremely useful. with that said when tuned full stiff the bilsteins are firmer and i actually prefer them

even stiffer is when GS turned my konis into coilovers (obviously) - if you ever plan on doing this the konis are the better investment

YMMV, but everyone I know who did a suspension swap with Eibach pro's and Koni yellows, blew them. Also, I drive on 16's, and find the Bilstein comfortable. The OP also stated low and stiff, in which case, the Koni's are not a good move. Reports come in from many places that they blow out when aggressively lowered. Lastly, speaking purely as conjecture, I believe the bump-stops in the Bilsteins are bigger, and thus, you are more apt to hit them when you hit a howler of a pot hole. This would make the ride seem firmer for sure. To put things in perspective on how "hard" the Steins are; my dad has a 06 9-5 ARC (the midgrade one) and I cannot compress his suspension by shoving down on the front fenders, whereas my car, equipped with the mean and nasty Steins can be.

I have the koni kit on my viggen for over 60k miles and zero issues

On the old spg's I used koni's on two cars with intrax and one with brad at kc saab's adjustable springs, I think I did 550/750# springs..... Intrax I loved until I tried brads springs.... Never had a single issue with the konis with either setup, matter of the springs being to low of a spring rate with intrax. Had excellent luck with the stiffer adjustable spring and koni.... Attended maybe a dozen track days with the adjustable springs and koni's, only a handful with intrax/koni. Best improvement I had in stopping power was the ap racing brakes

I chose Bilstein shocks because I have previous positive experience with them on older Saabs. Considered Koni, but I wasn't interested in adjustability, and they were more expensive (at the the time).
