MP3 is regarded as "better" depending on the context and the unique use case. However, MP3 files are generally smaller in size when compared to other audio formats; they are one of the most widely supported audio formats across various devices; they provide adequate audio quality; they have been around for a long time; and they have a substantial historical catalogue of music available in this format. MP3 files are also well-suited for streaming music over the internet due to their reduced file sizes.
