Which is harder to get, Kelly or Birkin?

I'm curious to know, in the world of luxury handbags, which is the more elusive and coveted item - the Kelly or the Birkin? These two names have become synonymous with elegance and exclusivity, but which one truly stands out as the ultimate prize for the fashion-conscious collector? Do the intricacies of craftsmanship, the limited availability, or the storied history of each bag play a role in determining its desirability? As someone who appreciates the finer details of these high-end accessories, I'm eager to understand which one truly takes the crown when it comes to being harder to get.
