I kept my E91 with 6MT and sport pkg for my daily driver.
have never driven a 335 and do not have functionality for an E92.
The E91 is fantastic. perfect sized car for the commute and the steering feel is better than my F10. have autocrossed the E91 also and it's a hoot. definitely "fun to drive" and very smooth MT with easy heel-toe. if you can find one with an MT, get it they're a rare breed.
