Combining REST Get Queries into Single Snap

I have a two part question.

I have to perform 3 queries to extract information from an application. I can put all 3 queries in the same REST Get snap. First question is…is this better or worse than using 3 separate REST Get snaps?

Second question depends on answer to first question.
If using a single REST Get snap is fine/recommended, the result is 3 tables. One field in each is the same between them. How would I merge these together to make one nice data stream? For example, if I have organization id shared between the three tables, how do create one table where these are joined together?

If using a single REST Get is not recommended, I’m assuming that using 3 REST Gets and a join would be the proper approach to getting the result I’m looking for…is that correct?

Thanks in advance.
