That depends on the task I guess.
In fcbpaint I use one interrupt per frame because cpu control is needed over the whole screen area anyway.
For a program where asynchronous code needs to run in the background using several interrupts makes sense. In datapop there is a 256 cycle stable NMI running + 1 non-stabilized IRQ per frame + asyncronous buffer filling code running in the background.
