Mechanical solutions can come in 1 of 2 categories:
1)actuated: These are basically the same as electrical solutions but a human moves the part instead of an electrical thing that adds an additional layer of complexity.
2)passive: Passive is always better.

the difference is wether code does the logic or a human does. Users tend to find 'electrical' solutions which are really electro-mechanical to be more appealing but a pure mechanical solution has one less part that can fail.

This isn't true in all situation and I do have an engineering bias but yeah...
