For pine I would shoose tha last one as well. The first one dont look healthy enough and looks to have a quite ugly swelling in the base. Maybe the swelling can be hidden in some smart way, but then you loose nebari.
For me Spruce is not out of the question. I would assume that it depends on which climate you are in. Where I live spruce is a good and easy growing tree. However, it is hard to establish the branches, needs to be wired several times before they set.
Depending on price I would go for 2 and 4. But as LB said, you need to pick what you like, not what anyone else like.
