A have installed a new exterior door frame to my stucco house and I still need to seal the perimeter before the winter rains. However, since I plan to repaint the exterior stucco a different color next summer should I use a paintable caulking instead of silicone? Is there a silicone-like caulking product that is superior to others?

So... the word "caulking" refers more to its use/application as a linear gap sealer than it does to the material composition; Caulk can be made of most any material (including silicone), it's still called caulk.

Yes, as was your intuition, you need paintable caulk. Some silicone-based caulks are advertised as "paintable", but for myself I am dubious of the claim because I fear that over time the bond of paint-to-caulk will fail. For paintable applications I use a high-quality paintable latex caulk.
