This really depends on what you intend to use your guitar case for and how long you intend to keep your guitar in it. If you are literally just looking for something to keep the dust from affecting your instrument and will be taking it out to play every other day then a gig bag or soft shell case could be perfect for you. It offers portability and flexibility whereas a hard case is much more rigid and sturdy. If you want to take maximum care of your guitar or intend to travel with it a lot, we would highly recommend investing in a good quality hard case.
