Hello EB’ers. My dark age has lasted for about 20 years, but after buying and building DUPLO for my daughter, i’ve refound the joy of LEGO. Recently i bought the Creator Expert VW Transporter, and I enjoyed every piece of building again! I’m hooked! Therefore i’m thinking about buying one of the bigger sets: The Hogwarts Castle, 71043, or the big roller coaster, 10161. I’m hoping, that there’s a few AFOLs out, who owns both sets. Which one did you enjoy building the most for the first time? Which one is the “Best” for building, picking apart and building again another time? In short: what are your pros and cons for both sets?
