Database & Dataset - basics

I can get the same results using

  1. wixData.get()

  2. or to attach a dataset to the page and use getItems( ).
    What are the pros and cons for each of the options (note that in my case, i don’t need it to connect any element via the editor)?
    Thank you

I thought that was a very basic question that anyone experienced can easily answer. Isn’t it?
