I’ve done training in both, and Vegas. Living in Alaska. Vegas was relatively cheap for a big city, great conditions to fly in. San Diego was great to fly in, very expensive to live in. I did love the crazy airspace around SoCal and it was fun to get used to that. Alaska flying is a lot of fun, weird airspace around Anchorage, but expensive. Also expensive to live in, cheaper than California but not by much. I’ve flown in the winter here plenty of times and I wouldn’t say you get thattt much crazy different experience to warrant a move just to say you’ve done it. Flying in the winter and preflighting in the winter gets old, quick. There’s not much more to learn from it that you can’t learn out of a textbook. I’d go to Florida, phoenix, or Texas to be able to fly (relatively) cheap and to live (relatively) cheap, or bunk with mom and dad and fly at your home airport. SoCal and Alaska flying are both gorgeous and you learn a lot but it’s not worth spending the thousands of dollars more unless you have another reason or want to move to these locations, or excessive amounts of $ to play around with.
