BLE Audio supports bidirectional audio up to ±1300kbps ("2Mbps" but with overhead subtracted) which is a LOT better than HFP, especially with LC3 as a replacement for the older codecs.
I don't think many devices support it yet, but the spec has a perfectly acceptable bitrate for modern audio calls. We just need to wait for hardware vendors to pick up on BT5.1 features. Last I read about these I think the focus for BLE audio was on hearing aids and such, but there's no reason the spec couldn't be used for headphones.
BLE audio also allows for things like connecting your headphones to multiple sources and broadcasting audio to multiple receivers. The standard has improved significantly, but without cheap, mass produced chips, these advancements will probably be stuck in expensive purpose-built devices for a while.
