I agree with Dov (rare) in that on long downhills I feel the difference on my road bike simply that I roll farther and faster without pedalling. But that's it... that's the only time I claim to feel a difference.
There aren't enough mountain descents in West London to justify the cost of ceramics, but I still put them on my road bike as I am lured to the reduced maintenance. This only works if you have ceramic on ceramic... steel races for ceramic bearings potentially reduces time between changes (impacts such as potholes can smash the bearings... and don't even think about it for off-road use).
So they can be worth it if you're maintenance averse or lazy on that front... and they can be worth it if you have a road bike and many mountains to shoot down... but just for cycling around London? No, they're as useful as some shaved legs.
