Is escape velocity the same radially and tangentially?

Say I was on the surface of the moon (because I want to avoid atmospheric effects) and I fired a gun. Would it be easier for the bullet to escape if I fired it at the horizon or if I fired it straight up?

The escape velocity remains the same; however if you shoot in the same direction as the rotation of the Moon around its axis, you'll get that velocity added to the bullet's velocity counting towards the escape velocity. Effect is maximum at the equator !
