They both have vertical form. I might foster some of the more spreading branches on the smaller one, or think about doing that, kind of try it out.
Do you know about pruning? If I thought there was a heaven, I'd plan on being given pruning shears when I entered..
If you don't, now would be a good time to read up and start to notice well pruned trees around town. If you will not end up doing it yourself, you can develop an idea what kind of pruning you like so you don't get a tough surprise from a garden helper. A good nursery might have some specific tree pruners (it's an art) to give names of, to check out their work. (I tend to think it's a good job if you don't really notice the pruning of a tree - except perhaps immediately after pruning - but do notice what a nice form the tree has.)
