Aeon Nova 10 vs Nova 14

I am about to buy an Aeon Nova laser, and am debating between the Supernova 10 and Supernova 14. I think the 10 makes the most sense, but then as they say "bigger is always better...."

I know it will depend on what I am making - but part of the problem is I haven't decided exactly what I want to specialize in. I'm but thinking likely signs, cutting boards, ornaments, and other customized items. I currently have a glowforge and have made a wide variety of items. I want to now take my laser work from a hobby to a business to supplement my military pension.

For those who have an Aeon Nova 10 how often do you wish you had a larger work area? Do you wish you had bought a larger machine? What do you make (or want to make) that would be easier with a larger work area?

For those who have and Aeon Nova 14, how often do you use the full work space? What are you making using the full work space?

(I'm hoping this isn't a constantly asked question, but nothing came up when I did a search)
