I lived in Texas in the 60’s. For me it’s just too darned hot. And too cold in the winter (lived near Fort Worth). And, truth be told, if there was no such thing as air conditioning, I wouldn’t live in KY. In Seattle, AC for your house was not really necessary. Here it is an absolute requirement. In your car, too.
But it’s amazingly green and beautiful here. And the roads! It is a motorcyclists paradise.
If climate is important to you, the Mountains of Western, North Carolina or Eastern Tennessee is really nice, particularly in the Summer. The Vanderbilts liked the area around Asheville.
Actually Northern Georgia is pretty good too.
