It's different depending on where you go in the SE. If you want mountains, East Tennessee or Western North Carolina are pretty rad with lots of outdoor activities and public land. Asheville NC has a bit of a PNW vibe going on (not something very prevalent in the South). The winters are quite mild but if you ski or board you'll be disappointed. If you want beach the Gulf Coast of Florida and Alabama are hard to beat. I'm from the PNW and moved to Charleston SC a couple of years ago from WA, it was really hard to leave but I'm 20 minutes from the beach and 3 hours from the mountains. The food is great, people friendly, and cost of living a little lower.
