Enjoy watching people play a sport and get better and better at it? Hajime no Ippo and Major (all seasons) both give you exactly this.
While Goro (Major) is more on the "genius" side, and Ippo is more on the "hard working" side, they both strive toward their goals with extreme passion. If you enjoyed one, you'll definitely enjoy the other.
If you enjoy sports anime, this will be a good watch. Similarly, both have characters "grow" throughout their careers and depicts their fight against stronger opponents and how they manage to overcome them.
Major covers baseball, which has more aspects to work with as compared to boxing, due to teams being involved. This also means more characters to develop (although HnI does develop its other characters too) and a heavy focus on teamwork.
