Choirs are being replace by Praise Teams, WHY? And which one do you prefer ?

In the past years an increasing number of congregations have started using praise teams and their are less choirs. What is a praise team? Are these chosen singers have a special anointing ? It is a group of four, six, eight, or more singers who lead singing as a group. Some praise teams will have a dominant soprano voice as the primary leader with others as supporting leaders. Other groups will use a blended group with complete equality among the participants. Some churches will place the praise teams on the pulpit where they lead singing in a visible manner. Other churches will place the praise team in the congregation where the church will not see the singers but can hear their voices over the voice amplification system.
