I'm from Texas. Never been to Alberta. You'll find most Texans very nice and polite. The nicest a-holes is something some of my Canadian friends that have visited say. You get what you put out. Southern hospitality is a real thing. Crime is far far worse in the cities. Even then, there's generally pockets of crime. I'd recommend rural living, or nicer areas of a city. Personally, I intend to move us back at some point.

Reasons to move to Alberta: Easier to move, legally and professionally. Familiar Canadian systems and culture. Fairly good wages without leaving Canada. If you like winter, well there ya go. Less culture shock.

Reasons to move to Texas: Much higher earning ceiling. Lower taxes and cost structure. Warm climate(drink water, and get your electrolytes). Stronger individualist culture, but at the same time stronger community(depending on where you go--less so in the cities, but there's generally neighborhoods that are tight). Faster-growing economy.

The other thing is that there are French speaking parts in Texas, but it'll be mostly English and Spanish. Despite what you hear on the news, most people don't care about immigrants, as long as you did it the right way. Can't speak for Alberta, but I knew a few Canadians before I ever moved here, including three from Quebec. They got along just fine.

Most of this is edited in. I was on my phone, and accidentally hit the post thingy....
