Help me, BA: Which tasting order? Gose or Stout?

I'm tasting and doing reviews of Sierra Nevada Otra Vez and Stone Coffee Milk Stout. Which should I do first? I typically do sours last, as they tend to destroy my palate, but I also like saving the sweetest beer and/or typically the stout as a nightcap. Which would you experts recommend?

 

Sheer curiosity drove me to going with Otra Vez first, as this is only my second-ever Gose. Fortunately, this isn't intensely sour in the slightest, so I don't think it'll effect my tasting ability much. In fact, you know what this beer reminds me of? Fucking carbonated lemonade. It's light-bodied, fizzy, mildly-tart and citrus-forward. I could drink a hundred of these.
