Generally i think either is fine because pro installers would already have 50-100 of there prefered type in there kit anyways and the included extras would just be for the one off installs that people dont do on a regular bases.
I also like to give some added feedback on the power lead part if I may. Now a days I tend to use compact / shallow cages when building up network cabinets because of the limited space and its a big help when the included power cable has angled fitting so then your switch can make it tight with the back of the cabinet making better use of the space when needed.
