What kind of exercise is better for bodybuilding, body parts for parts, or full body?

I need to know what kind of training that produces better results. Training Split, devote your training sessions set for a body part, such as weapons. Or whole body, making the body an entire training session. Also please give reasons for their answers. Thank you. In fact, the champion of 38 years, you're wrong. I learned that the routine body separation is much better for the results, thanks anyway.
