For most people, an "acoustic guitar" is generally considered better if you want a versatile instrument that can play a wide variety of genres, while a "classical guitar" is better if you specifically want to play classical music or prefer a softer, mellower sound thanks to its nylon strings, which are easier on the fingers for beginners; essentially, the best choice depends on the type of music you want to play. 

The best guitar tuning depends on what style of music you're playing and your personal preference. Here are some of the most popular tunings and their uses:
