I've never owned either, just have a friend who bought a very expensive labradoodle for her son, 5-6 years old. After a month she was going crazy. It had so much energy. She took it to obedience school and took it on long walks. She could never get it totally potty trained. She ended up selling it to another person who wanted one. I know of people that love them and they have had no problem.....so I think it depends on the person themself and what they are willing to go through to get past the puppy/teenage stage.
One labradoodle in our extended family. Way more energy and strength of will than any dog ever in our family. Cute as pie, and quite a comic, but a hand full.
