None are real easy to get on, so go through Ricardo. A lot of people on the site prefer Olivos but different strokes for different folks, its a good track but over rated imo, too much hit it here, exactly here, no not there you will go in the trees. Buenos Aires golf will have the best putting greens if that flips your switch. Nor Delta is tough if you really want to be challenged. Jack has a signature design a Little further outside of B.A. that is fairly new and probably better than Nor Delta called Pilara. Not the prettiest time of the year but playing off semi dormant or dormant close cut tiff fairways is the best, especially if there firm and the greens should be rolling quick this time of the year. If they have had a lot of rain, Nor Delta would move up the list because of it´s superior drainage.
