Between sodium hydrogencarbonate and magnesium hydroxide,which is a better antacid and why?

(N/A) Magnesium hydroxide,$Mg(OH)_{2}$,is a better antacid than sodium hydrogencarbonate,$NaHCO_{3}$.
Magnesium hydroxide is insoluble in water,so it does not cause the $pH$ of the stomach to rise above neutrality,preventing the stimulation of further acid production.
In contrast,sodium hydrogencarbonate is soluble in water. An excess of it can make the stomach environment alkaline,which triggers the stomach to produce even more acid,potentially worsening the condition.
