Congratulations Lewis Hamilton on your F1 achievement. Reviewers usually compare current champions to past champions but the scale is not the same.
Technology is so advance now that it’s hard to compare two people in different times to see who is better. Unless they compete at the same time, for instance, Lauda and Hunt… And even then, different cars and budgets. If you want to compare two people and see who is better, then give them the exact same scenerios and you will find out who is the best.
