I agree W&P were probably better technical dancers, but that doesnt mean that A&S werent possibly slated to medal at the 86 worlds before their mistake. As you know ice dancing is very political and being Soviet in those days was always an advantage. There are some who felt Wilson & McCall should have even been better than bronze sometimes, but there was never a realistic chance of that unless 1 of the top 2 Russians fell.
I agree Annenko & Stretenski's strengths were best shown in the compulsories. Their free dance at the 87 worlds was also very interesting and original, perhaps the most of all the top teams and IMO should have scored better. However most of their programs and choreography as amateur was forgettable, as pros they had much better material and really came into their own, perhaps due to no longer being constrained by the rules.
