It will be especially useful in good sounding rooms. Therefore, the microphone need not be aimed in a certain direction. This means it picks up sound evenly from all directions. The omnidirectional microphone has equal sensitivity at all angles. It is easy to get a good signal as the cardioid pattern blends out a bad sounding room, a noisy fan in the background, etc.

You can use this for most recording applications.

This isolates it from unwanted ambient sound. The most commonly used pattern is most sensitive at 0° (the front) and least sensitive at 180° (the back). The most common types are: Cardioid, Omnidirectional, Unidirectional, Bidirectional. The pick-up pattern of a microphone is the sensitivity to sound relative to the direction or angle from which the sound arrives, or how well the microphone "picks up" the sound from different directions.
