1. Weather... if you are comparing Patagonia Arg to Chile yes Arg is more dry. On one hand rain keeps you indoors on the other hand it means the grass is actually greener in Chile. I traveled back and forth between Pucon and Chile every 3 months to renew my "tourist" visa. The difference is noticable. If you suffer from dry skin you will feel it in Arg and not in Chile.
2. Prices... tough one because day to day living in Chile is a lot higher but with the subsidies on gas and utilities in Argentina the low prices are an illusion and when the subsidies are gone the people will riot in the streets. Chilenos run around unplugging everything and Argentines leave everything running all the time. We noticed about 20 percent inflation per year in Arg and in Chile it's steady. Prices of land and houses in this region are much lower than anywhere in Patagonia Arg.
3. Gringo friendliness... you never know what is said behind your back but more people speak great English in Arg than Chile. Chilenos are known to be gringo friendly but sometimes they just see dollar signs. Argentines are more relaxed about things I would say. For example my kids classmates in Arg had about a 50 percent divorce rate and here it's about 5 percent. Much more conservative with that.
5. Residency... You need to research the famous (sort of new) Zona Frontera law regarding ownership of anything in Patagonia Arg from Mendoza all the way to the end of Arg. Realtors will tell you they can get around it but it's just not true. You must be a naturalized Arg citizen to actually hold title to any property and this is not an easy task. You can certainly give your money and live in a house or have land but when it's time to sell or you die and can't pass the property to your kids it's a bit messy. I strongly suggest researching or getting other opinions from someone with nothing to gain financially from you. In Buenos Aires it's not an issue. In Chile it's simple to get residency and even tourists can hold title to just about anything. Word of caution about owning cars. No foreigner can leave Argentina in a car that they own. This is a very old law that should be changed. Chile does not have this law.
Look beyond the typical tourist places like Pucon. The tourism board has their own agenda but living in a tiny town has it's own problems so be careful with that. Another important factor is basic infrastructure and Chile has my vote. I hope that I never have to fly into or out of Buenos Aires again. Travel to Patagonia Arg is expensive and impossible. Chile has great roads and airports. Travel within Chile is a dream compared to Argentina. Sometimes I go out of my way to drive on a gravel road just to remember Argentina
