Wet cast generally more uniform though wouldn’t worry too much about it.
What you going to be driving over them with? If it’s only a tractor and mixing pump 5t should be enough.
I’d buy the cheapest and put rubber on the back half of pen. Just get them to guarantee gap width to be uniform and will be no problem fitting rubber.
