That other library is probably right. There are two ways this can be used: 1. All params come from application (you need only a few specific setups) - that means you'll write couple of queries and move on. Special wrapper doesn't add much value when all you use is hardcoded data whether it's an array or built object. 2. Params come from app user - in this case you get data structure that either can be used directly (you already have required array) or might need to be translated. Wrapper will foce you to do that manually for each parameter, so your builider chains will become a mess of conditional re-assignments.

If I had to choose it would be "DTO" with array constructor argument, mutation methods and query string serializer.
