Medellín edges cheaper and more predictable right now, great for steady adventure like nature escapes. Buenos Aires gives more urban buzz and nightlife but watch the swings. Tips to keep it low in both: Eat local markets, negotiate long rents, use public transport, get basic private health add-on if staying longer. Both let you chase affordable thrills without constant money worry. Pick your flavor, mountains or tango, and go live it! Stay safe and enjoy the ride.
