I'm really impressed with difficult entrances but don't like creative exits, because exits are less risky. If a landing is not quite right, the skater can just forego the creative exit. But with a difficult entry, there's basically no way around it.
I like both.
Especially when they're successful, of course.
With a difficult entry, even if the jump itself is not successful, the preceding choreography is still more interesting and valuable than a telegraphed entry would be.
With a difficult exit, yes, often the skater has to leave it out if the jump wasn't landed successfully.
So in that sense, relying on difficult exits to increase the Transitions component and the complexity of the choreography in general is riskier, because it's more of a gamble whether the skater will be able to execute the choreography as planned at all.
...--and Jeremy Abbott's exit out of his triple axel (i think it was in the 09-10 program) .
This one? I included the approach as well as the exit because both impressed me. He has also used that approach in other programs. But when the axel wasn't successful, the connection between the jump and the subsequent spin lost its intricacy.
