@brad5 is right that the combined wisdom is to keep the bulbs on the Hue bridge and accessories on the HE hub. More recent advances in the Hue platform, though early in their existence, allow for updates to Hue devices to be pushed to external systems, such as HE custom integrations, catered for by the Coco-Hue and Advanced Hue Integrations developed by @bertabcd1234 and @armand.
Along similar lines, there is also expert advice from @ogiewon re the channel selection for Wi-fi and Zigbee networks.
I may have over-complicated things.... So, given your small setup, I would personally suggest whatever is easiest at the moment, keeping in mind all that has been suggested, then adjust your setup as you encounter any issues.
