Yes imagequality should be exact the same, it is only if you have high stealth needs ( current models are by no means huge / un-stealthy in most installs ) or if you really must have parking guard but live / park in places that get really hot, in which case the DR can be put in a colder location than on the windscreen in the sun.
The DR should also be as good as they get if you want to use it as side cameras, but side glass Vs windscreen and rear window are another beast so have to be creative here.
In my case i have a little fixed glass on both front and rear doors, so the Dual Remote K2S test camera i have i have put on the fixed glass on my rear doors.
