Being a former Texan, if you like the outdoors, you will love Oregon.
I really don't have any dislikes about Portland, I guess it depends on what side you move to and why.
I prefer Northeast and East portland, its centrally located to everything.
Concerning hunting, depending on when you arrive, there is the Oregon Waterfowl Festival which is a 2 day event that should give you a good intro to the popularity of waterfowling up here.
Feel free to send me a PM if you have specific questions.
