I also have to acknowledge they'd be lucky for their groundbreaking exploits in the 70s to make the free skate at a WC today.

Wow! What a statement. If either Cranston or Curry were born and developed within the current skating era, they would either be ice dancers or else would possess the jumping skills and artistry to beat most of the men's field or be top competitors.
Would that some of today's current skaters were taught more about these guys' amazing creativity and how much they revolutionized men's skating back-in-the-day!

I would also include John Misha Petkevich, Robin Cousins, Robert Wagonhoffer, and before them, Dick Button, Ronnie Robertson, Donald Jackson, and the brothers, David and Hayes Jenkins.
Without all of the amazing skaters who came before, the way forward would not have been paved for Scott Hamilton, Paul Wylie, Brian Boitano, Brian Orser, Kurt Browning, Yevgeny Plushenko, Alexei Yagudin, Sasha Fedeev, Patrick Chan, Daisuke Takahashi, Jeremy Abbott, Adam Rippon, Denis Ten, Jeff Buttle, Stephane Lambiel, Alexei Urmanov, Johnny Weir ----- who all served as the bridge to the current generation that roughly began with Hanyu, albeit there is overlap as DTen was a contemporary of Hanyu (plus shout-out to MKolyada who was so exquisite at his best). Leading on to Jason Brown, Shoma Uno, Nathan Chen, and now Yuma, Jun Hwan, KevinA, AdamSHF, DenissV, MikhailSha, Ilia, et al. The men's field is the most exciting today because these guys were freed to express themselves fully on the ice as a result of the burdens previous generations bravely faced and overcame.
Cranston and Curry are giants among the earlier generations of male figure skaters. It is counterproductive to try and compare the technical skills and official requirements of an earlier era to what is being done technically by today's athletes. If you want to compare skating skills, creativity, and artistic abilities, Cranston and Curry win by a country mile.
