The two sports have something in common, but Tai Ji Chuan is a little more complicated, because there are many schools in Tai Ji Chuan, including Chen, Yang, Wu, Wu and Sun. There are many branches of each sect, each master has different movements and styles, and there are too many routines to learn. That's easy. Relatively speaking, there are only eight sets of health qigong, and all of them have unified action standards and requirements, which is relatively easy.
