Why can't you compare over decades? Surely the GOATS list should start with those who dominated their era's and were head and shoulders above their peers at the time. That's why in my GOAT list the top 5 are Messi, Maradona, R9, Pele, Di Stefano. In that order. All dominated their era's, conclusively.
Messi
Pele
CR
R9 was phenomenal but I don't think the majority includes him in the GOAT conversation. It is usually among Messi+CR, Pele, Maradona, Di Stefano, and Cruyff. For me this is the ultimate top tier list. May have forgot someone. R9, Beckenbauer, Zidane, Xavi, Iniesta, Best, Puskas, Garrincha, Eusebio, Platini, Yashin and the likes are a tier below.
As others said though, comparing players who played in different eras is a bit pointless. But I do think that after all is done and dusted, CR will be mentioned as a top-3 player.
