I'm not about to go to bat for Mongo in an SQL thread (there's plenty of problems with that platform that are real), but I rather enjoy their query syntax, it's very AST-like, even through the aggregation pipeline.

I don't believe it's probably much faster even in the best case (and I'm sure an experienced SQL expert wouldn't find it any "easier"), but on a grammatical level I do find it a fresh take on query structure, and writing queries and map-reduce jobs in coffeescript was extremely satisfying because of how terse, elegant, and pseudocode-like it turned out.
