The Amsterdam Seed Banks are always a good option to start with. Sensi does this job for decades, so nothing wrong with them.
Greenhouse was very strong last 20 years with marketing. Especially the Strain Hunters series. Point here is, Franco the head breeder of Greenhouse died 2017. He was the brain the last years. His strains are fire. Last strain he worked with is sold as Franco´s Lemon Cheese. Couldnt find it on my last Amsterdam trip.
Barneys is old school Amsterdam coffee shop. I am finishing a grow atm with all three of them.
For now (not smoked yet, still drying/curing) the best looking plants are the Persian Pies from Greenhouse.
Also i can recommend Serious Seeds. They have very iconic strains like their AK 47, Bubble Gum or Kali Mist.
Another Amsterdam based seed bank is DNA Genetics, might be worth a look.
From Dutch Passion i stayed away all the years. I remember i heard from someone that they are good for the masses but not good for the lovers. 10+ Years ago though...
Royal Queen seeds is a young company compared to the Amsterdam breeders. It is a spanish company, they have some good genetics for sure.
They are cheaper compared to the others.
