Is a Gamecube Controller (Switch) worth it?

The Gamecube Controller (To Smash) Costs around 100 Euro…
And on Amazon is a controller that costs around 40 euro
and in addition is wireless.
Should I then the controller of the 100 euro cost of a cable has… (https://www.amazon.de/Nintendo-045496430856-GameCube-Controller/dp/B07DQXQQG3/ Or the controller is the 50 Euro cost and wireless (https://www.amazon.de/Power-Wireless-Controller-Purple-video-Noir/dp/B07GXKCX6Y/

An original GameCube or Pro controller is the best choice. It does not have to be this special edition of the GameCube controller you've linked. A stink normal has exactly the same functions. But you have to keep in mind that a Gamecube controller needs an adapter if you do not already have it.

Would the 50 Euro controller also need an adapter, or would it then connect to the switch "automatically"?

The connects without problems. However, he only looks like a Gamecube controller externally. The buttons feel cheaper. The shoulder buttons are also those that do not exist in the actual one.

Okay well then I stay with the adapter so have a Gamecube Controller Thank you.

Then it's good. If you need help with the game, I can help you.
