It depends where you live, how much money you want to spend, and what you want out of a bear. I love to hunt bears, but I've never went on a guided hunt. So my information isn't as valuable as some others.
I've hunted bears in Alaska 5 years, Idaho 2 years, and Montana 2 years.
If I could go anywhere, I would go to Alberta or B.C. Idaho isn't too bad, but the majority of the bears aren't large. The prices in Idaho are a lot cheaper.
If your looking for color, and size, check out the Peace River area in Alberta. I've heard there are some big bears there and a guy has a good chance for a color phase? I hope this helps.
