As Valerie mentioned, MF & 35mm are quickies, LF is a long slow... rack and pinion focusing, knob twiddling. I wanted a 4x5 camera so I could do proper sized alt process prints as opposed to my box brownie 6x9 negatives. I like close up shots and the 4x5 camera is quite good at that without needing extra lenses.
I have patience for craft, less so for process, whatever gets me there in the end.
And honestly I like developing sheets singly as I could never really finish off a roll of 35mm. I have a few rolls of 120 hanging around in some cameras too, one of which has been in there for definitely over 6 months. It's almost more immediate, in that context, that I can shoot something, pop it in my paterson tank (yeah I know I'm weird), pour in some rodinal-y water, shake shake shake, 15minutes later I can see how the exposure was and in the context of my self portraits, if I got the focus right or the composition right.
