What's the Point of an Annual Subscription if Your First Choices are Sold Out Anyway

Hey girls, I've been living vicariously through all your Spring box choices posts! I'm debating whether I should buy an annual subscription or not. In some of the threads, I've seen people say that some of the Bobbi Brown options are sold out. I thought that getting an Annual subscription protected your choices since there's less people you have to beat to cop your main choices. I've also seen other comments say that things sell out so fast for Seasonal subscribers as a shady tactic that FabFitFun uses to push you to upgrade to an Annual subscription so you can get first dibs on what you really want. But as it appears, even if you upgrade to Annual, there's no guarantee to get what you want, so what's the actual benefit of upgrading at this point? Thanks in advance for your perspectives!
