I shoot almost all my shots with 35 mm (the rest is MF with a Holga). I like grain and find the flexibility of 35 mm suiting my way of working. I like shooting people and 35 mm gives me the ability to shoot a lot of shots before changing film. I could do the same with motorized MF camera but would have to change magazine for every 10th, 12th or 16th shots instead of every 36th! I like my Canon and when I almost never make larger prints than 24x30 I can live the grain.
LF is for the old people who can't keep up the speed of 35 mm and cannot see unless they got the image blown up on their 8x10 GG
