Eco lifestyle added one of the most complex systems in the way the eco footprint works. It does affect, like the others said, every part of the game. I also like the grunge aesthetic and the industrial b/b. The community lots make the world feel more alive and juice fizzing is one of the most fun skills ever.
Cottage living on the other hand has one of the most fun challenges you can play in this game in simple living. Also the world is very beautifull.
I chose eco because I think that in the long run raising animals is going to get boring.
