Never thought I'd want a 4 cyl. motor. Never thought I'd feel sportiness with an AT. Never thought I'd focus on balancing options/tech goodies with performance. Things have changed.
I chose the 328i because I preferred its feel and handling characteristics which are truly outstanding and found it to have more than enough power. The decision had nothing to do with cost. The car really comes alive when the handling is challenged. In your situation where you're going to trade off options against mainly engine difference, I think the decision is easy. The options in this car are a really enjoyable and significant part of the experience.
I would prioritize as follows:
The sport auto provides a separate, sportier experience that works really well with the AT. You might save it for the funner roads but when used it would likely rekindle your love of the car. And both the 335i and the 328i are cars you can love.

Never again anything larger than a 3 series sedan.
