How is this any better than something like flatbuffers though?

For one, Arrow is columnar.

The idea of zero-copy serialization is shared between Arrow and FlatBuffers.

This is explained in the FAQS for Arrow, saying they use flatbuffers internally. Arrow supports more complex data types

Only for IPC support - Arrow data format does not use flatbuffers.
