Go to guitar shops and play everything there. There are a lot of factors to consider. Don't be swayed by popular brand names. Just because a guitar has a name you've heard of on it doesn't mean it's a good guitar. It also doesn't mean it's right for you.
Every individual guitar is different.
Don't be a snob and refuse to look at unknown brands. You might miss out on something special. Some cheap guitars have tops made of plywood. You don't want that, because over the years the guitar will pull itself apart. For acoustic guitars, a spruce or cedar top is ideal.
