The draft order opens the checkout page directly and applies the discount without the discount code. Simply put, the draft order works the way Shopify’s “Buy It Now” button works.

The main difference between the Draft Order Bundle and Discount Code Bundle is, you can track orders from Google Analytics or Facebook pixel in a discount code bundle which you are not able to do with the draft order bundle method.

If you are using multi-currency then use the Discount Code method, Draft order method does not support multi-currency.
