They're all fine, but what are you going to do with it? For example, Epson has 3 44" wide printers and each are great for their specific uses. The 9700 is for corporate graphics, quick copy printers, that sort of thing. The 9890 and 9900 are for fine art and high end printing (there's some overlap) and the 9900 is also great for commercial print proofing.
So, you have to be more specific about what you do and you probably still won't find any consensus here.
