A digital piano has many benefits (especially if has the full 88 keys of a traditional piano). These include, never going out of tune, more than one sounds, sounds are recorded from high quality instruments, can be silent (when headphones are used), take up less space, and are more portable.
My sister is a classically trained pianist whose teaches the piano and she prefers a digital piano for all these reasons. They can also be cheaper than traditional pianos.
