So many things to consider. The advantage of an Epson is you will get factory service. It had a lot of issues when it first came maybe those are resolved. Ink between the two printers is similar in price. Realize if you purchase a Mutoh the company you are buying it from is the company that will have to perform warranty work so that becomes critical. You will want to make, especially under "warranty" that you purchase your ink from the same place you purchased the printer. Make sure you ask about how they perform warranty work especially print heads as that is basically the first thing to go south. There are a lot of RJ900 out there for good reason. It is a quality product and pretty easy to work on. Even at that if the Epsons have improved and pricing was similar and it was my first wide format I would get an Epson just to have the comfort of knowing that if something happens you have one call to make.
