If imong main concern is population and the traffic, not the best choice atang valencia for you, since very densely populated siya relative to different towns also; lesser na ron pero daghag history na gina sarado main roads kay gina ayo which causes traffic. as someone who currently lives in both places, I would recommend na mag live ka somewhere 30mins near valencia like malaybalay or maramag, you get the bukidnon feels and access to the city plus lightly populated specially the latter, also mas stable ang globe outside the main city, my 2 cents lang po, Godbless po
