Nest devices via SDM or HomeKit

Hi. I am a newbie to HomeAssistant and have successfully setup HA on a Raspberry Pi 5 and had a question regarding integrating Nest Devices in HA.

I have my Nest devices working in HA using the SDM integration, and am also using HomeKit integration for sensors in the home. It looks like HomeKit can integrate some of my Nest devices (Smart displays, Google TV) as well.

Is the Nest integration or HomeKit integration better from a stability, latency perspective?
