>If data to be passed is flat (records) and not complex (hierarchical records from different tables), and for fast performance, you can use simple arrays that can be created with Select-SQL, or even can passs arrays (one or more) attached to an object, so you can pass the object reference and from that you can show directly the array data or generate a cursor with INSERT FROM ARRAY syntax. This way you can avoid the complexity of collections and can debug directly too. Arrays are faster than collections.

100% agree - both arrays and collections have pros and cons
Experiencing both may help make one's own opinion
