Z6100 vs 11880

[whoami]

We are going to buy a new wide format inkjet soon and we need to make the decision between an HPZ6100 or an Epson 11880.  Anyone have any experience with both printers?  I have heard that the HP has some bronzing problems and has problems printing on glossy media.  Anyone have any recommendations as to which printer we should purchase?  Pros Cons?

I use a hp5000 and an epson 9800.

prefer 9800 for single sided proofing and poster production
