Well if you compare it to other crop sensor cameras like the rebel series I like it A LOT better! Comparing a 60D to a 5D3 is like comparing a Fiat to an Audi.
Better auto-focus system, 8fps continuous shooting vs 5.3fps, 100% view finder (96% on the 60D is annoying), less shutter lag, better button lay-out. If those things don't mean much to you go for the 60D.
