I’m currently doing the MLA at the Wageningen University. Wageningen started as a agricultural university and this left traces in the current MLA program. Focus lays on (Dutch) rural areas. Much emphasis is laid on analysis on social/cultural, ecological, economic, political and meanings and aesthetic values. The design process is based on a problem solving approach. Delft is more focussed on the urban environment with a great emphasis on social/cultural and has a more ‘art-based’ approach.
The masters in Wageningen and Delft are fully thought in English. Outside of the universities you will be perfectly fine with the English language. In fact a lot of (younger) people in the Netherlands have English as their second language.
Most important is to think what you want to learn and discuss your wishes with the study-advisors of the different masters.
