They're both right. This also applies to speakers. One may have very good, flat bass, but only go so low, where the other may go lower, but have less flat frequency response. Depends on the buyer. Good speakers are carefully designed to achieve a balance of performance that matches the priorities of the designer.
Some designers put much of their budget into appearance.
Some designers put their budget into very high efficiency. Others strive for the smallest box which can deliver an acceptable low frequency performance. In an effort to make movie soundtracks more dramatic and engaging, Dolby Labs created a signal encoding which encodes more than just two channels of audio onto the stereo signal. Many popular receivers and home-theater systems include the required circuitry to decode these signals. These components are referred to as Pro Logic, Dolby Pro Logic, or Surround Sound components.
