Others have commented on the financial/utilitarian aspects. So I wont spend much time on that.
Atlanta, GA has more greenery than the average Texas city. OTOH, Austin has a great "keep Austin weird" vibe, whereas Atlanta is more of a soul-less megalopolis.
The point I am making is that you need to visit and preferably spend a week or more in each place before you decide where to move.
e.g. I dislike the arid landscapes of Phoenix, love the mountains around Denver, dislike something about Houston and Dallas (not quite sure exactly what) and can probably only grudgingly tolerate Atlanta, GA. I had no idea that I had these preferences before I visited these towns and spent some time there.
Even after all that due diligence, please don't fully commit till you have spent at least one or two full years in that area. I have two retired neighbors who moved to Florida after they retired, but hightailed out of there after the first rainy season and came back to CT where they can see the familiar "4 seasons".
