Even when you take out the licensed themes, Lego seem to have more current themes than Playmobil. Pirates seems to have made a return, possibly due to the continued success of Playmobil's pirates, and their Castle theme is still going strong.
Lego seem more inclined to add humanoid monsters like trolls, squidmen, and aliens, and I'd like to see more of these from Playmobil. So far bunnies and space aliens have been the only non-human humanoids.
