Originally vanilla logic is to use stream, and Mojang switched it to Guava's Collections2 since 1.21.4. It is much faster than using stream or manually adding to a new ArrayList. Manually adding to a new ArrayList requires allocating a new object array. However, the Collections2 lazy handles filter condition on iteration, so much better.
