It depends on what your use case is, I have both homebridge and homeassistant setup for different devices. But I also use HomeKit as the main hub of my home automation not home assistant.

For me both services are primarily for things that don't natively support HomeKit (my vacuum, logitech harmony, the receiver for my sound system, and a couple other things).

I also use home assistant to expose a couple of fake accessories for state tracking for some automation, and I do a little bit of more advanced automation in home assistant.

I use both though since some plugins in the home assistant side are way to complex (and causes issues due to that complexity) for what I need to just expose controls to homekit, or don't work as well as the homebridge version.
