Design a database with or without inheritance

P: 4
Hello,
I am trying to understand inheritance and how to use it with PostgreSQL. For this reason i design a database in the excel file. In the 1st columns you can see the table w/o inheritance while in the 2nd part of the sheet you can see the tables with INHERITANCE.
Can you give me your opinion and help on the following?
1. Which is the best design ( w or w/o inheritance )?
2. Is my design with inheritance good or sth is missing?

I am looking forward for your answer.
Thanks in advance
Elias
