Premier League experience these days doesn't tell if a player can do well or not, let's take a good look at Isak how he became one of the finest striker in the EPL, even on his first season we saw how he performed by helping Newcastle to be one of the teams that causes problems for the top teams in the EPL. From what I have seen from both players, talking about Xaxi Simons and Eze, I feel Eze would be a good match for the Arsenal squad. He can be the next option for either Odegaard or Saka since these two guys doesn't have a better replacement. After Arsenal released him at the age of thirteen till now I feel going back home would be a great addition to the squad now that he's much better and has improved than they saw him back then.
