Epson 18100 or Surecolor F100?

Hi all, I'm looking to buy a new dye sub printer after my 5 year old Epson L805 stopped printing colours correctly and mottled once printed and all attempts to fix it have failed 😫

I've had a read through printer recommendations on here and think I've narrowed it down to two possibilites;

Epson 18100
Epson Surecolour F100

Anyone using either of these printers and can share your thoughts?

Any others worth considering? I print bone china mugs, ceramic decorations and ceramic coasters.

Thank you 🙂
