Guitar and Piano are amazing musical instruments and very similar in their potential.
I've been teaching in school and privately for over 60 years and playing professionally in just about every kind of group, setting and musical style.
Don't just learn something. Understand it.
Learn how to make music on these instruments (either or both), faster and easier than anywhere else. I teach composing, arranging, reading, and improvising because they are all related and it's easier to learn it than not.
It is important that you know how to read music. Tablature for guitar is not music, it is "paint-by-numbers". It is harder to read than music and gives you much less information and understanding about what you are or will be doing with the music.
