First Response or Clear blue for early pregnancy?!

Which was more reliable when you first found out you was pregnant first response or clear blue? I tested with first response and got a positive ( tested twice both early morning) but got a negative with clear blue ( tested in the afternoon btw) .. Which is best to determine your pregnant at the earliest ?
