None. EcoTanks are not the latest and greatest thing out there for printers yet. They're still in their first generation and have a terrible setup for regular maintenance. Meaning when it's time to service, you'll most likely need a replacement if the software cleaning options aren't working.
I would recommend a laser printer but you mentioned borderless printing. However, getting a Canon Pro-100 or Epson Artisan 1400/1430 would be great with a CISS kit installed. You'll save a ton on the cost of ink and have the borderless cleaning option. Plus maintenance couldn't be easier.
