I agree and disagree, they are perfect around young kids. We got ours 2 years ago when my kids were 5, 3 and 3. She did want to nip at their heels and herd them, for about a week, she trained out of this so easily it was ridiculous. And she had a herding instinct, her parents were working sheepdogs and she was the last of her littermates to be collected, most were gone at 8 weeks, we collected her at 12 weeks, so there were times she was out with her parents. She still wants to run after a diesel engine (the tractors on the farm were diesel) as a result of this. She is amazing with children, she listens to and obeys commands, protective without being aggressive, loves attention, playing and cuddles. You are right that they need stimulation and exercise but so does every dog. We used to have a husky and they didnt need the same level of stimulation but they needed twice (or more) the exercise a collie does.
