Shimano Tiagra 4700 - my opinion about this drivetrain

The latest version of the Shimano Tiagra 4700 drive is very often seen in road bikes from 3,000 to 6,000 zlotys. There are 10-row cassettes, a modern design four-arm crank with two or three chainrings, and rim or disc brakes. Is it worth being interested in such a drive? Or maybe add to better equipment? In this episode, I will consider whether it is worth having a Shimano Tiagra drivetrain.
