I think it depends on when you started following Michelle's career. After all, she competed at the highest levels for a decade.
At first she was regarded as a prodigy jumping bean, mastering all her triples (minus the Axel) by age 12. At this point she snuck off against the wishes of her coach and tested for U.S. senior status. At Junior Worlds that year, she was the best jumper and was especially praised for her triple Lutz-double toe combination (judges weren't so fussy about flutzing back then. Both Midori Ito and Kristi Yamaguchi had done 3Lz+3T earlier in the decade -- in fact, both at the same competition (1991 Trophee Lalique) but this skill fell by the wayside for a decade or so afterward) -- maybe except for Surya Bonaly?).
Michelle had a 3T+3T combination in her early days, which she landed about half the time (14 times in major competition in all). She practiced two endings for her programs -- if she hit on the 3T+3T then she did a split jump at the end, and if she missed the triple-triple she did an extra 3T as her last jump instead to bring her triple count up.
Anyway, by the time Sasha Cohen came along, many others had caught up and passed her technically, though none with enough consistency to knock her off her perch. At 1998 U.S. Nationals the buzz was that other girls would be going for the triple flip as the solo jump in the SP, instead of the triple toe. Michelle had no choice but to make the upgrade, too. Although she was spectacularly successful at that competition, delivering perhaps the finest SP of her career. still the triple flip was never her favorite and sometimes let her down, for instance at the 2002 Olympics.
In compensation, though, by this time-- the middle of her career -- she was so far out in front on the second mark that she kept on winning U.S, and World Championships until chronic injuries began to take their toll.
