I hope the title says it all really. Are you a pixel peeper or an image admirer? Do the pixels really matter, do they spoil your enjoyment of an image, can you look no further than a little noise and dismiss things based on the pixels alone? Can a noisy high ISO image still be good, or is it totally spoiled for you and it gets dismissed out of hand? Or do you look only (mainly) at the image and realistically the higher ISO noise mean very little as long as the image is good?
