Although a computerized sewing machine generally has more features, mechanical sewing machines are not without their perks:

Affordable: with fewer features to start with, a mechanical sewing machine is usually cheaper than a computerized one. If you are a budget-conscious sewist, this might come as a big benefit.

Simplicity: More advanced features mean more to learn. If you are not sure about what you are going to use the machine for, you may end up wasting most of a computerized machine’s functions.See here:
