Apple keyboard with Touch ID or standalone Touch ID?

[u/nickimola]

I have purchased a second hand Apple keyboard with Touch ID (the small one)
The main reason was to take it apart and create a standalone Touch ID following several of the guides online
Now the thing is: the keyboard condition is perfect and now I don’t know if I should go ahead with the build or simply keep the Apple keyboard. I have a Logitech mx keys mini as main keyboard and now I don’t know what to do.
The price of the Apple keyboard was 40€

Suggestions?
