You can  choose to use gauge pressure or absolute pressure, but whichever kind of pressure you choose (gauge or absolute) must also be used on the other side of the equation.

Dear student,
Taking gauge pressure is also fine, it just removes the atmospheric pressure which is anyhow applied uniformly on the system. But equation of Bernoulli mentions the use of absolute pressure.
