I personally really like using the Hue Bridge. It provides native integration with Amazon Alexa, Google Home, Apple HomeKit, Logitech Harmony Hub, as well as Hubitat, Node-RED, Home Assistant, etc... I find it nice not having to un-pair and re-pair my devices to try out various integrations. It also makes it simple to keep the firmware on the bulbs up to date, allows for the bulbs to retain their state after a power loss, etc.
