Despite similar roles, they are really different players. The big difference between the two is that despite being over 2 years younger, Sochan is much smarter and higher feel, with an understanding of how to play on both sides. He consistently makes reads and is in the right place defensively. He anticipates and rotates, but he won't make a rotation that he isn't supposed to make. He generates fewer steals and blocks, but gambles less and is more positionally solid. He fouls way less than Eason. He moves his feet better defensively and reaches less.
Offensively, Sochan is a much smarter and more willing passer who plays well out of short roll situations and handoffs; Eason is a black hole. His handle is tighter than Eason's IMO and he is less prone toward turnovers, both because he is a really good passer and Eason is not and because of the handle. Eason also has this quirk where he absolutely can't finish with his left hand, and so if forced to his left hand he will still try to finish with his right and the results are not good, resulting in frequent turnovers and blocked shots.
I think Eason has a better chance as a shooter, but it's dicey either way. Both guys will definitely take shots, which is a good sign. On short shots, neither guy has great touch but Eason's touch is worse in my opinion.
Positionally, they are both strong, big wing sized and probably project to play the same position (4, with the ability to switch onto guards at times and bang with larger guys at times).
Eason in college was mostly an iso player who attacked relentlessly as a ballhandler and generates a ton of foul shots, but was a poor passer. He leverages his strength advantage offensively as a driver, but I worry about how that advantage holds up in the NBA. Defensively, he was very impactful but high foul and makes a bunch of mistakes. Eason is a project and is going to drive his coaches crazy, and as an older player may never develop the requisite feel level to play in the NBA.
If you have a couple hours and enjoy this stuff as a hobby, I really like these cutups of shot attempts, assists, rebounds, turnovers, and defensive possessions on the season. Gives you a much better feel for the player than highlights or scouting report videos, but doesn't take nearly as long as watching full games. There are things you can only get from watching games, though, so not saying it's the end all be all.
