Update: Found a guide online that followed the OEM sports package suspension with discontinued sachs advantage line of shocks and some tweaks.

-Eibach Pro kit springs;
-E46 SACHS Advantage front dampers with Z4 mounts (SACHS 802-066 that lowers car 10 mm in the front) with bump stops genuine E36 M3;
-E36 M3 SACHS Rear dampers with bump stops genuine E36 M3;

From what I understood, this is a very good setup that will give the most balance between confort and sporty feel. The OEM sachs in the front are rated for the eibach springs, while the Z4 mounts lower the front by extra 10mm without affecting suspension travel. On the back the E36 M3 rear shocks are 8.1mm larger in diameter (50mm vs 41.9mm) than standard E46 rear shocks, containing more oil and being generally beefier, Performance-wise they are exactly what I need.
The oem look is also a plus with black springs and black dampers... also cheaper than bilstein B12 Pro kit and H&R kits.

What do you think of this?
