I'm going to have to disagree. Lifting weights can build mass and straight line push/pull strength way quicker than calisthenics. On the other hand, calisthenics cut me up/shaped me in the way I want to be built better than my weightlifting did and doesn't limit my body speed like heavy weights do. I found that focusing on weightlifting was great to get to my desired size, but I like the overall shape that I am getting by focusing on calisthenics. I prefer being built like a gymnast/bar athlete than a bodybuilder.
Herschel Walker is someone who got his build primarily from calisthenics. He is almost 50 years old here:
Weightlifting or calisthenics all comes down to what your desired purpose for strength training/fitness/bodybuilding is. As of right now, I do a mixture of both weight lifts and calisthenics, but with more focus on calisthenics.
