TCKline user here. My choices were narrow due to xDrive. TCK is one of the few options for AWD BMWs.

My E91 drove like a Buick (no kidding) on OEM suspension. The feeling was floaty, imprecise, and generally uncontrolled. The Koni yellow-based TCK dampers with revised valve rates really transformed the handling from soccer-mom car to proficient track car.

I can't comment on the other options since I have no first-hand experience with them. If I were in your shoes I would consider the TCK or Ohlins. KWs strike me as being in a different user-group. No flames, simply my personal opinion.

The TCK camber plates are very slightly noisier than stock. I didn't notice them at all after a couple of days. They are not intrusive in any manner, other than giving a wider range of camber options that you will appreciate if you drive in a "spirited" manner.

Consider your intended use for the car. IMO, daily driving is fine on the OEM suspension, if rather Toyota Camry-like. If you drive with 'brio' or track your car, I consider TCK SA or Ohlins as entry-level dampers for this application.
