6GK5 OR 6AH5 for phono head amp

Which might be the better choice between these two valves with a view to building a phono head amp to compare with my present Jfet Hagerman ? I was decided on the 6AH5 but keep reading that Conrad Johnson used the 6GK5 for the initial gain stage on one of their better known phono stages. Or is it a question of not what you use but how you use it ?
