This is a weak xin metal day master and the balance of the chart can only be maintained if the earth stars are in the stems. Unfortunately, the earth stars do not protrude in the stems and the chen-xu earth stars are also clashing with each other. The wu earth stars involved in the clash are his DR stars and this can affect his sense of comfort. The chen-xu clash also affects his ancestor palace which means there is possibly a yin house fengshui problem.
I will definitely choose the earth protruding luck pillar as his best luck pillar since earth stars will balance the qi flow of this chart. Water -> Wood -> Fire -> Earth -> Metal. Wu-xu or ji-hai?
In the ji-hai luck pillar, the hai will clash the si while in the wu-xu luck pillar, the the chen-xu clash will be activated. Between the two clashes, the earth clash is not necessarily bad because it will release all the protruding stars. As long as the balance of the chart is maintained, the earth clash is still alright. So, I will choose wu-xu as his best luck pillar.
