If you could only have 1, which would you choose?
Some points to think about:
Is the extremely shallow depth of field on the 5D mark II a blessing or a curse? Does the low light performance of the 5D mark II at higher ISO's outweigh the 60D's articulating viewfinder? Is the 5D mark II's tendency to overheat more so than the 60D a big deal? What about 60FPS, or the lack of it on the 5D mark II? Does the "full frame look" counter the slight increase in aliasing and rolling shutter compared to the 60D? The 5D mark II also has superior build quality and weather protection.
