So I'm currently planning my anniversary trip to Argentina. We're travelling for 2 weeks, and I'm thinking of a 3 destination setup.

Currently I have Buenos Aires (5 Days) -> Bariloche (4 days) -> ???, but I'm stuck on the last destinations that being a close match between Iguazu Falls and Mendoza. Both seem like really amazing places to wrap up the trip but I'm having a hard time deciding between them both.

We're mainly trying to balance affordability, relatively low-stress logistics and memorability.

For anyone that's been to either or both which would you choose, and anything we should look out for or also consider?
