I don't live in either one and have never played on either of the golf courses, but some other factors may be how big of a place you want (and lot size) and whether you prefer the privacy of a gated community versus one with parks and trails that are open and accessible to the public. To my knowledge, the smallest home you may find in Golden Eagle may be around 2,500 square feet, while Southwood has a much larger range, although not many of the smaller ones back up directly to the golf course. While GoldenEagle does have more homes that back up to a lake, Southwood has more trails (especially paved) that surround the ponds, though these are also open to the public.
Both are very nice...good luck!
