GPS altitude/Altimeter indication

Hello everybody, I read that GPS derived altitude should not be relied upon to determine aircraft altitude since the vertical error can be quite large and no integrity is provided. If I fly an aircraft with a GPS installed, do I follow the altimeter or GPS altitude and why? Thanks in advance!
