Go back and look at some old posts of mine (in the suspension forum, on mobile not easy to look up right now), I had a 2010 128i Sport package car, and I did the M-control arm upgrade up front (2 per side). The impact harshness went up significantly after the upgrade. Sure the feedback and feel were great but I hated the sacrifice, and the upgrade to me wasn't worth it.
Some people say it's the tension strut arm that has most impact in ride harshness. I can't confirm or deny that...but...I hated the final result.
If you're not tracking and/or were happy with the feel prior, just go with OE replacements in my opinion.
