Feel like you trying to play it off as "slightly older" is pretty misleading. PCA was 2 years older than Chourio at every single level he was at. That's a huge gap. PCA was in A and A+ when Chourio was in the MLB. PCA was in AA when Chourio is entering his 2nd MLB season after putting up a near 4 WAR season in his rookie year. Comparing him in any way to Chourio is pointless. These are very different level prospects and players.
PCA can certainly be an All Star level player and will very certainly be an annual 3+ WAR guy because his defense and baserunning are that good, but he has not been a good hitter in both AAA and the MLB. His hitting success in the minors was pretty much entirely in A, A+, and AA.
