I would disagree with that. Perhaps at a lower kyu level that may hold true because you can do you own thing and get things straight in your own head at your own pace.
But at a dan rank level I would disagree quiet strongly with that. I find having friends at around your level helps to push you along at a quicker pace. It's much easier to thrash out problems in your technique with friends than with strangers. If there is a problem with your technique friends are more willing to point it out than 'non-friends' are, especially if they are kohai.
