FAQ entry: https://clojure.org/guides/faq#transducers_vs_seqs
Both have their place, in my opinion. I often use transducers with `into` where I would have used ->> in the past, but not always - it depends on context. While transducers will generally perform better if you have many transformations or large (reducible) collections, lazy sequences (which automatically leverage chunking and transients) are surprisingly fast. Additionally, in cases where won't actually use all of the result, lazy sequences are faster by avoiding work that doesn't need to be completed. Transducers also don't cope well with potentially large or infinite intermediate results (even in the context of `sequence` with a transducer as transducers are a pull-based model).
