So the Basic vs Main cabin doesn't change the seat experience, just no seat assignments until the end. I wouldn't count on being together with your wife, you'll be likely in middle seats.
If you check a bag it is $60 one way on Basic. Main you get one free up to 50#.
The comfort seats are more leg room and that's very valuable to me. (I'm 6'5)
