Web application SEO

Hello,

I have a technical question for SEO experts that have worked with web applications.

I have two applications that display multiple questions and answers that may get asked by users in a Google search. These question and answer pairs are stored in JavaScript objects like such:

{Question:"What is the meaning of life?", Answer:"42"} 

The two applications have different methods of loading and interacting with this data.

App 1

• The questions are stored in a JSON file on another URL. The application uses the fetch method to load the data and display it.

• The user reveals the answer by scrolling over the question.

App 2

• The questions are stored on-page as a JavaScript object and no fetch is required.

• The answers are revealed on click when the user clicks on the question button.

App 2 may have better on-page indexing and increased user engagement with the clicks, but would this offer a significant boost to ranking? It may also decrease loading speed of the page, but I have not calculated this yet.

Any insight is much appreciated.
