Yes, the PTB (Chamonix) have better spec as a viewcamera in almost every point.
But, my aim with the Toyo is to have sturdy well protected clamshell package with a lens mounted for traveling. To get that I'm willing to let go of the better features on the PTB. So for my requirements for this camera usage the Toyo is a better match.
And I have a nice Shen-Hao 5x7 FLC (with 4x5 back) and a 8x10 deardorf when I need to do all the other stuff wich the PTB does.
