For me, it's mostly a matter of ergonomics and usability between the two.
60D has a pentaprism finder with more coverage and better magnification. This translates into a bigger, brighter viewfinder image.
I prefer to have a top LCD for my shooting style.
I like the control wheel on the back of the camera for changing settings and playback of photos.
I prefer the bigger grip (this is a primary reason why I won't buy a rebel - it's not comfortable for me to hold."
The specs are fun to sift through, sure, but to me, actually using the camera, and it's in-hand feel, are most important.
Of course, the reasons why I love the 60D may be the reasons you hate it.
