there's some viewfinder comparisons on this site:

it's down to the camera and how much you spend. The d60 might be better than the d70 in some/many ways but it's aimed at a lower end than the d70 was when it was released. The d90 is really the current successor to the d70.
I have my d70 still and like you was impressed when I had a play with a canon (1dmk2) due to the large and clear viewfinder among other things - but i now have a nikon d3 which is even better
At the end of the day my mate takes better photos with his old D70 than I could ever hope to with any camera
