Don't really think it matters which Hwy the poster meant. We bought south of 466 over 4 years ago because we bought new. We still love our location and at first thought it was superior to everyone else's
With repeated visits (we have been snowflakes/landlords) have discovered that every area, north or south, east or west, has its advantages and disadvantages. There really is no BAD area. Wherever you end up, you will probably think that yours is the best, and it will be for certain things (close to shopping, or softball diamonds, libraries, or town squares, dog parks, Savannah Center, quieter with less traffic, other shopping areas, woodshop, driving range, favorite country club restaurant or golf course).
Older areas have more mature landscaping, larger lots. New areas may have a higher concentration of younger buyers, but not always. In each area, you could be within walking distance or a 3 minute cart ride to a rec center and/or family or adult pool or country club, or you could be out of easy walking distance to anything and need to take your cart or car. Some people never walk anywhere, even if they are around the corner. You will be close to a golf course no matter where you end up.
If you have close friends or family you expect to be visiting a lot, then you may not want to be at opposite ends which would be a 45 minute (or possibly more) cart ride. But it's kind of fun to visit someone occasionally in an area you don't get to very often.
