Same experience here, Philips (and other Zigbee lights like IKEA) did a great job.

Only problem I had with the Philips hub is that it's memory limited and can't handle more than about 50 devices. Above that you need to replace the hub with something like Home Assistant, but can keep the rest of the system.

You can also use multiple hubs (HomeKit and various third party apps support this - the Hue app does, but IIRC you have to manually switch between them).

Yes I considered that, but it made some use cases that had buttons control lights that were on different hubs impossible.
