Most people will say their generation - or to be precise the generation during which they grew up in - is the best of all time. That's pretty obvious, but there's research to back it up which shows that experiences are lived most intensely around the ages of 16-18. A lot of other factors to consider though, such as the difference made by harder tracks, better drugs, etc in athletics, the sports where there has been a lot of fat to chew off, the sports which are only played by a small cohort relative to the most popular sports.
