Not every rippled tile creates the same atmosphere. Some have barely perceptible undulation, while others have pronounced waves or ridges that become an obvious part of the architecture.
A subtle ripple is generally easier to carry across a full kitchen or bathroom because it adds depth without dominating the room. More pronounced relief can be extremely effective behind a vanity, bath or cooker where you want the wall to have greater visual impact.
It's also worth thinking about what else is happening in the room. If the flooring has strong pattern, the worktop is heavily veined or the cabinetry is highly detailed, a quieter ripple may create the better balance.
On the other hand, in a relatively restrained room, a stronger rippled tile can provide the detail that stops the space feeling too flat.
