Everything seems to be in Observables in Angular, so after a little experience, you get good at going between the two for your needs. I think it helps you master async techniques in general. I tend to use .pipe(take(1)).toPromise(); all the time, but never go from Promise to Observable. As you said, they have different uses, depending on the data source.
