I suppose to some extent this is a matter of taste, but I've usually found the streams api to be clearer and easier to understand, although perhaps there's a bit of a learning curve. I think the win is especially large in cases where you replace an anonymous inner class with a lambda, imho. At my previous job, we had all gotten quite familiar with Apache's CollectionUtils, but java8 almost obviates the need for that entirely.
