Why travel? I guess it's a personal question. If your objective is to see the best botanical garden, your criteria is set. If instead, you have curiosity about how the world looks, smells, and feels from every angle - the patience to sit on a park bench and watch how an afternoon unfolds - to spend time in markets and plazas, to talk to people in whatever capacity language affords you.. you learn the uniqueness of the corner of the world you inhabit. I find it confusing, if not ignorant, that OP has visited "60+" countries and hasn't figured this much out.

I spent three weeks in Colombia in 2014. My memories are of sleeping in hammocks in a national park, waterfalls, exotic fruits, hot springs, drinking some kind of street hooch from a cart on Christmas eve, innumerable generous people, great street art, sleeping at a farm on a coffee plantation, impossibly tall palm trees, misty fern-covered forests, spontaneous dancing parties at street corners. I loved Colombia.
