In honor of Elizaveta Tuktamysheva's successful triple axels of late, here's a comparison of all the ladies who have successfully landed a triple axel at least once at an international ISU competition.
Midori Ito
Midori Ito was the first lady to ever land a triple axel in competition. Ms. Ito's technical abilities as a jumper was so insanely far ahead of her contemporaries such that she is, to me, the Niccolo Paganini of ladies figure skating insofar as she was a phenomenon rather than a development. Put into perspective, when Midori Ito won her world title in 1989 with a triple axel, the most difficult jump in Katarina Witt's world title-winning program in 1988 was a solo triple loop. Similarly, Jill Trenary's gold-medal program at 1990 Worlds had a solo triple flip as its most difficult jump. Admittedly, Ms. Ito's competitive results in the earlier days of her career can be attributed to the role of compulsory figures, which Ms. Ito was known to be rather poor at. But as the numerous technical-mark 6.0s Ms. Ito received in her programs attests, the phenomenal quality of Ms. Ito's jumping ability cannot be denied. In the two decades since Ms. Ito retired from competitive skating, her triple axel still arguably stands as the best ladies triple axel ever. For proof, I submit the following exhibits:
