I can't comment on the current stock, as I have not been able to get my hands on any locally, however the search continues. When I was in the gun business in Germany, left in 1998. GECO was part of the RWS family, and was what the "white box" equivalent is to Winchester, a lower cost sporting grade.
If it was pure junk, I can promise you the German sport shooters would not buy it, Plinking is not part of the vocabulary.
I did own more firearms in Germany, than I currently do, yet everything revolved around competition shooting, and following the rules and traditions around it. Many of us were also active reloader's, and junk was not tolerated, after a 3 day required schooling, and the cost involved to get an Explosives License, you expected quality product.
On the other side since for the most people, there is nothing to compare against, they could be shipping their seconds to the US.
My SIG 210 is sighted in for the GECO 124gr 9mm, so I am still out on the search to find some.
If you do try some, let me hear about the results.
