Cheviot trees are good ( cell grown  I think are  better than bare root cost isn't much more.... )

Main thing that seems  important  in establishment from what ive seen is the first summers weather and early vegetation/grass control/mulching etc as less competition   over the first few yrs

Im not sure how much  bare root whips vary in quality from one another from different suppliers....

Press Heath Forest Nurseries and Heathwood Nursery are both excellent.
