Well, at the moment, I would pick ZywOo in his current form, over s1mple in his current form. If I had to pick between ZywOo in his current form, and s1mple in his 2018 form, I would take s1mple.
EDIT: I understand that people's memories fade with time (or they never knew), and they think that the way a player is right now, is what they were all the time. That's why we see so many comments/threads mocking device's mechanics, Olof/GTR's skills, Rain's skills, s1mple's skills, etc. 90% of these people probably never saw those players in their prime. Well, I have seen what prime s1mple can do, and I would take that over anyone else. At the moment, I would choose ZywOo.
PS: Of course, I respect your opinion. Have a nice day :)
