Most any pump sold today will pull a system down to an adequate vacuum. We can debate this point or that point about JB vs YJ vs Brand X all day. A pump is, for the most part, a pump.
More important for good, deep and fast evacuations is the stuff that you put in between the pump and the system.
Make sure that you've got good core remover tools, good, large internal diameter hoses and a good micron gauge.
