Learning Piano.. Should one invest in a Piano or being a beginner should learn on a keyboard 🎹.. Would learning be easier on either one of them?

I would get a relatively inexpensive digital piano. They have weighted or semi-weighted keys, 88 notes, they sound great, and don’t take up much space. They can also use headphones , or internal speakers. Brands I would consider would be Williams, Korg, Casio, Yamaha, or Roland.
