I played with both as a child, and I would have to say Playmobil was so much tighter than legos, my reasons
1.Playmobil was more expensive and sold only in high end non corporate toy shops.
2. Their Skiing play set was rad, in addition to their racing playset, construction play set etc.All their different toys were accurate and often teamed with companies like BMW or Mercedes or Bosch to bring added real world accuracy and helped develop brand awareness at a young age.
3.Lego was way too mainstream, and the different playmobil features were alot more realistic and accurate than the lego BS.
