South America is pretty amazing. I'd really like to go back - lots more to see! I've been to Argentina, Uruguay, Bolivia, Peru into Colombia up the amazon on a boat. Passed through Venezuela and sort of been to Brazil, but not officially.
Spent a few weeks in India this year on a couple of different trips. It's just a bit too mental. Too dirty, cows wondering about eating bags of rubbish, people being run over by drivers avoiding cows, dead dogs, people shitting in streams, etc. I'd love to go to the north though, by the mountain ranges. Seems a bit more chilled out and less dirt.
