It's interesting that in pic 3 they do look a little leggy. I guess that's just how they grow? If that's the case, I don't need to be worried about mine.
The Red Chokeberry does grow very upright and leggy. I often like legginess in shrubs, depending. Easier to plant other stuff around leggy shrubs. The Black species is lower and more bushy , especially if it is one of several cultivars from Chicagoland Grows.
I may have mentioned my aronia line that was planted in the spring. The nursery is giving me 8 replacements and of them, 4 are blacks. Since it's a hedge, I'm not too worried about the height difference but it may look odd if some are dense to the ground and others are not.
The Black Chokeberry shrubs may not be the compact cultivars and may grow upright to about 6 ft or more. I have a customer who has a mix of both and they are much alike in part shade.
