Which type of sensor is better, CCD or CMOS?

It is actually difficult to describe which one is better. CCD and CMOS are two different sensor types using different technologies. CMOS can be considered mostly digital sensors, while CCD are mostly analog sensors, with different drive circuit systems. Traditionally, CCD was viewed as high-end products and CMOS as low-end products (except sCMOS). But now the situation is completely different. With CMOS technology development, CMOS can achieve performance equal to or better than CCD. Sony has announced discontinuation of CCD products and replacement with CMOS because they have strong confidence in the new generation CMOS. CMOS has now become better in several aspects: sensitivity, noise control, and output speed. It is certain that CMOS will be the future.
