Every light in my house is Hue, and all rooms have those Hue dimmer switches mounted over the normal light switch.

I absolutely love it. It's never been anything other than instantly responsive, works without the internet and I can turn all the house's lights off from my bed. Additionally, the utility rooms, hallways and bathroom lights are just fully automated so you never think about it. The regular switches are still there if you need them, but in over a year since installing it, I've not touched any of the traditional light switches.

My only issue is that the Hue Bridge has a maximum limit for the number of lights and accessories you can run, which I'm starting to get close to. The lights are also expensive, especially the low voltage outdoor lighting, so for that I just use a standalone ZigBee dimmer switch which integrates with the Hue system.
