Bonds did better than ok. He was well above average by age 22 and never really let up.
To answer OP's question, I think PCA has the clearer higher probability path to sustained stardom. Elite CF defense alone gives him a higher floor. Average arm strength caps Chourio's ceiling relative to a true elite defender. Historically, elite CF defense and offensive output by age 24 tend to sustain high value for years.
Chourio has youth on his side but he's gonna have to show some real improvement next season to keep pace with PCA.
