If you talk to ten folks... you'll get ten differnt answers to any jm question including this one...you are more likely to get accurate info on SLOW growers...since it's not in most sellers best interest to advertise slowness ;>)and many want a tree to grow bigger faster ( with the exception of dwarf varieties whose growth by it's name is obvious). Alot depends on your growing conditions ...the same cultivar will most likely grow faster and bigger in the PNW than in wisc. or say AZ.where conditions are more extreeme either in summer or winter or soil conditions are not optimal...
You can also get pretty good info from Vertrees book but there is always an if that being location location location both in what geogrphical area... and area of your yard you are planting.
If you are looking for a basic JM that in most places and inviorns grows fast the basic red atropupurium is a good choice.. David

As usual, it depends. It depends on site conditions, it depends on rootstock used, it depends on cultural practices...
