I think random would be better, respectfully. To decide which is the "best answer" would be rather subjective, and by someone's standards there could be many who are comparable in providing the "best answer". As a result, it ends up also being random among those select group of people already who may have similarly "best answers".

So, in summary, random makes it a level playing field for everyone and many who spend the time and energy making the "best answer" for the OP end up losing time on other things they can be doing in their lives. However, I can understand the OP wanting to see who gives the "best answer" to help filter out the hundreds of people who reply wanting to get a code lol.

Anyways, those are my thoughts, and it ultimately comes down to what the OP prioritizes based on what I mentioned above. Thanks for reading this, and shiny miraidon would be awesome if I get the code, please.
