I'm going to be buying a new Hypertherm powermax but haven't decided on the 65 or 85 for my CNC table

my question is there any benefit to having the 85 rather than the 65 other than the thickness of the material it can handle, they both use the exact same consumables. I will be cutting no more than 3/8" maybe 1/2" once in a great while, A36 steel

will i get more total inches of cut or total number of pierces say for example 1000 inches of cut on 3/8" with the 65 and 1250 on the 85? Or will the consumables wear out at the same rate no matter what, I know the 85 will be able to travel faster but I'm not worried about production speed
