This is entirely based on personal preference. If it is the kind shown in the picture, it is inconvenient to work and easy to scratch. Note that a smooth surface will not be very basic, but it will look better from an aesthetic point of view. On the other hand, this model is mechanical and the price will not be high. To sum up, you can wear the model you like, or change it according to your mood and environment, and the price is not expensive.
