For me both work as dualities, 15/17 being the more physical and sim versions, while 16/18 being the more “arcadey”, but with better feeling when you control the ball, makes you feel more free. I have concluded that this comes as a cost for PES games , physical VS response ,they can’t yet build a game that relies on both of them. As for 2015, I love it too, but it is the greatest example of how a but UI and XUI can hold back a game. Even with a decent gameplay in the old-gen PC version, all the inner menus, except for the main outside menu, are bad designed, laggy as hell, unergonomical as hell, you need to go deep inside 3 slowpoke menus just to put a player on transfer-list, the presentation of the player stats is terrible, they tried to rush them using the stats screen from the Facebook app manager game (for anyone still remember) “PES association football manager” , where only stats displayed are Tec-Speed-Physical, which was a terrible shortcut. Also the entrance scene was available only in competition finals, or only on PC unlocked by sider.exe. Finally the edit mode, limited in ps4 to no OFs and in PC to just use images was like telling : if you don’t use third part patches and tools and you want to rely only on in game editor , you will suffer to death. It was as the guy created it , wanted to torture us all. Just to be fair, the main menu of 15&16 is of the best and well represented if any pes. The rest submenus are terrible.
