Correction: 35mm is grainier, not noisier. After staring at grain vs color noise in shadows for hours at a time, the aesthetics of grain are one of the reasons I still shoot film sometimes.
This is somewhat of a good point, I like film's aesthetics too. But, grain and noise are two different inter-related things.
A digital full-frame sensor (vs 35mm film) at the same settings is going to have much less noise. I love film. But the fact is that silver vs cmos is a losing battle of technologies.
