Using classes/IDs vs. nth of type/nth child selectors, etc

Is it usually preferable to use classes/IDs, etc when we can, and stick to using nth of type/nth child selectors only when we have to or when we have no access to HTML? I guess what I'm asking is, are these selectors part of a standard design process or kept for more of a last resort scenario? Thanks!

They should be part of the standard design process and can be used to easily select specific child elements that otherwise would be very cumbersome to code. In cases of dynamic content they may be the only solution.

For me they're really useful when it would be too inefficient to add classes to the html. For instance if I had a long <table> element and I wanted to alternate the colors of the rows, it would be much easier to use even or odd nth-child CSS rather than add a class to every other <tr> in the html.
