jones I don't think it is overrated, if a player has PL experience usually means they will settle in quicker. Zinchenko may be injured a lot but his performances have generally been outstanding. Also there is always a risk when you sign anyone from a different league, for whatever reason they might not hit the levels here. It is a lot less common for a player to move within the league and not hit their previous level.
It is less common now I suppose but there have been a fair few players who come from abroad and it can take them 6-12 months to get used to life on and off the pitch in a new country. Players like Pires & Henry took 6-12 months to settle in whereas players like Cazorla & Monreal settled in quick.
