One thing that gave Euler a huge leg up against his peers at the time was his invention of functional notation. I think it is a very underrated advancement he gave while others focus on one of his many formulas/theorems/etc. It also gave him the ability to work much faster and prove things quicker and get them published before others. Whereas Erdos definitely had to compete with people who had the same tools as Erdos plus the ability to focus in a single subject.
