lol - the qidi has larger print volume. Good company with good support.
Also the qidi is easier to fix and modify.

Both have the same connectivity.

It does depend entirely what you want to print.
for that kind of money I'd personally go for a formbot t-rex2+
The idex (independant dual extruders) take the hassle out of dual material printing.
And believe me with a fixed dual nozzle setup - it can be a real hassle.

The heated print chamber isn't as useful as you thnk it will be - unless you plan on using cheap nylon, or abs (no clue why people still use abs).

So it does depend what you want to print and with what material.
neither of those printers would be my pick at that price point lol
