I think Bose is a better company than Sony. Although Sony may be a more well known brand, I believe Bose makes better quality products. Bose speakers are primarily made for home use and many of their products are smaller and more accessible than some of the Sony speakers. Even small Bose speakers are capable of producing excellent sound quality.
More professional musicians may prefer Sony because their products can be used in large venues. Overall, I would choose a Bose product over a Sony product because I think the sound is better.
