Whatever your decision, I would be careful of a Graphic. They're cheap, but don't feel anywhere near as sturdy as the other brands. If you do go the Graphic route, use it with a Horseman back. Graphic roll film holders are crude, made of plastic that has often become brittle.
Where did you get this? The baby graphics were built to the same standards as the 4x5’s. They are tougher than nails. They were built for day in and day out heavy professional use by press photographers.
I haven’t used it in a while but I still have my 4x5 Pacemaker my dad bought new in 1964. I used it professionally for a couple of decades and it still functions like new.
In the mid 70’s I worked for the Department of Energy and each of us photographers were issued a Super Speed Graphic 4x5. They had been in use for ten years or more and tens of thousands of sheets through them. They still functioned and we’re still tight. I personally adopted a Speed Graphic issued during WWII with olive drab leather and military ID numbers stenciled on it. It worked like a new one with no issues.
I own several very old knob type wind Graflex roll backs. They keep the film flat and are not brittle and have no function issues. The only Graflex roll back that was a problem were the early ones made for the Graflex SLR. The rollers were under size and did not hold the film flat but they were designed for the Graflex SLR which had a different light trap and aren’t compatible with the Graphic spring back or Graflock backs on the press cameras.
I owned three Linhof Technika cameras at different times. My first was a Technika 70 with a 100 Planar, 180 Tele Arton and 53mm f4 Super Angulon, Rollex back and a few other gadgets. The second was a 6x9 Technika V with RF and same set of lenses. The third was a Technika V with no RF and a sweet set of 6 lenses. I had Linhof roll backs for all three.
The Graphic is very nice if you don’t need movements. What movements are on it are minimal and barely of any use. The rise is modest but might come in handy at some point. These were never designed to be a view camera. They’re small press cameras intended to be hand held.
All three Linhof’s were what you’d expect. Very very well made, very heavy and nice movements if you don’t need movements with wide lenses. The Linhof’s have ample movements with normal to longer glass but virtually none with wides.
Linhof’s Super Rollex backs are very heavy and are unique to the 6x9 system. No other maker made a back that fit a 6x9 body. They’re super expensive and heavy and complex requiring periodic maintenance. I’ve had a couple fail due to cast parts in the wind clutch fracturing. Let’s say very expensive repairs.
I thought about buying another late 6x9 Linhof but decided to just use roll backs in my 4x5 Ebony. It’s about the same size and a little lighter and much more flexible in movements and backs.
Personally I wouldn’t mess with sheet film. It’s expensive and the selection is slim and not available many places. Buy a Graphic roll back and whatever camera suits your needs.
There are quite a few 6x9 cameras. As mentioned the Horseman which I have no experience with, the Graflex XL which I think is 6x7 but may take 6x9, Mamiya press and probably a few others. My Brooks Veriwide has a 6x9 roll back and sheet film Graflock back as well. Great camera if a 47mm lens on 6x9 trips your trigger.
Attached samples from the 6x9 Linhof’s and roll backs. The two interiors were shot with the 53mm f4 Super Angulon and the exterior with the 100mm f2.8 Planar. All with the Technika 70. The film was Panatomic X probably in Microdol X.
