Plan 4 days for Buenos Aires and 3-4 for Rio. Buenos Aires needs Recoleta, San Telmo (Sunday market), Palermo, La Boca, and a tango show or milonga night. Rio needs Copacabana/Ipanema beach time, Christ the Redeemer, Sugarloaf, the Santa Teresa neighborhood, and a Tijuca rainforest hike or favela tour with a reputable operator.

Yes — LATAM, GOL, and Aerolíneas Argentinas run nonstop in 3 hours for $200-350 round-trip. The standard play is fly into Buenos Aires, four nights, fly to Rio, four nights, fly home from Rio. Add Iguazu Falls (a 2-hour flight from either city) as a midpoint stop for an extra two nights.

Both belong on a first South America trip if at all possible. If forced to pick one, Buenos Aires is the easier landing — better food, lower prices, a more European-flavored cultural texture, and easier daily logistics. Rio is the more iconic visual experience but the security situation requires more planning.

Buenos Aires — by a clear margin. The parrilla culture (Don Julio, La Cabrera, El Pobre Luis) serves some of the world's best beef at $15-20 a meal that would cost $80 in New York, plus great Italian-Argentine fusion (the country's Italian heritage shows). Rio's food scene is solid (feijoada, pão de queijo, açaí bowls) but doesn't compete on quality or value.

Buenos Aires for late-late nights — dinner at 10 PM, clubs in Palermo and San Telmo running until 6 AM, milonga (tango) nights in old San Telmo halls. Rio for beach-bar and samba — Lapa's Friday samba on the streets, beach kiosks with cold chopp, and the rooftop bar scene in Santa Teresa. Different rhythms; both excellent.

Buenos Aires has lower violent-crime rates and feels more like a normal European-flavored city in safe neighborhoods (Recoleta, Palermo, Puerto Madero). Rio has more security questions — armed robbery on city beaches at night is a real risk, certain favelas are no-go, and locals advise against visible jewelry or phones in public. Both are manageable with normal precautions; Rio just requires more vigilance.
