Yes and even if there was more material, it doesn't mean that it would be easily comparable as there are so many different things to consider when you compare players with each other.
But I think we are doing it right if we respect them both for their achievements, but I do understand if people have an easier time to like players more that were particularly a part of their lives. In my case this is more Messi and than Maradona, but frankly speaking, I could exactly tell whether one of them was truly better than the other player. What's impressive about both of them is the time they dominated the world of football. It wasn't just a year, not even just a decade, but around two decades.
I think we can't compare GOAT in each generation because each era has different rules and ways of playing which makes the reference very subjective. Maradona played in an era where there were no modern tactics that made team play very collective. In the past, it was very rare to find replays of matches or players, so it was difficult to find weaknesses in players like Maradona. This is different from today where coaches can provide advice and tactics to stop a player who is considered dangerous.But I think we are doing it right if we respect them both for their achievements, but I do understand if people have an easier time to like players more that were particularly a part of their lives.

But in the past, football rules were not as strict as they are today, so physical fights were a common occurrence, so great players of the past like Maradona had to have stamina and a strong physique to be able to dribble the ball well. I can't give any other examples but I would like to say that comparing players across each decade is something that cannot be done fairly.
This is right and frankly, it would be awesome to have all these players be able to play for a few seasons during a different generation. Of course I think that a player like Maradona would have been a crazy player in the 2010 Barcelona team with Iniesta, Messi and all the other guys. At the same time I think that a gifted player like Messi would have had great times decades ago as well. I think it is no coincidence that the goal Messi scored against Getafe was so similar to the solo goal that Maradona once scored.
As for the football rules not being as strict, maybe you should watch a video that is called the hardest tackles on Messi. I don't think it can get much harder than that.
But I even saw the news on some reliable sources. It is really a shame to see fake news on such reliable places.
