What is the difference between the Mimaki JV33 and the HP Designjet 9000?

I speak Portuguese, but I will try to say what I know about the two printers. I was in fair of signs in July and was in doubt about what printer to buy and just by deciding for mimaki jv33. The HP has 720 hp X720 resolution and the cost of the heads is very high. The mimaki jv33 have a lower cost of heads and has more resolution can have up to 1400 dpi. I am using the mimaki only one week, the the level of paint fell very fast,but is very easy to use.
