You are the second person not sharing which brand they think actually is good. I read only negativity, nothing positive here.

I happen to like De Cecco, and it's the one they sell at the local italian specialties store (Berlin).

I mentioned Rummo in my other reply: https://news.ycombinator.com/item?id=26074834

Rummo is great, their penne are almost impossible to overcook.

Agnesi is also a good brand.

I'm sure you can find both in Germany - I'm able to easily find both in Poland.

Agnesi seems ok and is available here in out-of-the-way Brazil. De Cecco seems fine but is typically more expensive for reasons unknown to me. Barilla is also sometimes present here. Most brazilian brands don't or won't use hard wheat, though the local preference is for mushy pasta, so I don't know if this is cause or effect
