I own a 60D. The video quality by itself is comparable to the 7D since it uses the same sensor but you need to be aware that it's cropped and not a full frame.
The swivel screen was the main selling point for me when I purchased the hardware. It's great being able to shoot pictures and video from all kinds of angles. To this day I love the camera for it's picture quality especially in low light situations with a prime lens. I've customized my picture profiles to get the best quality out of my video.
The only thing, and I mean the only thing that drives me crazy is the gimped audio features. If you plan to shoot audio, do it externally from the device. Even when using things like Magic Lantern on my camera I found the audio to still be too over gained and hissy and I think it's due to the internal amplifier. The lack of a headphone jack makes audio a complete nightmare since you can't really tell what it's going to sound like.
I purchased a Canon XA10 just a couple of months ago and couldn't be happier. It uses XLR inputs and I get crystal clear audio out of the device on 2 dedicated stereo channels.
You may want to consider looking at the Canon 5D MKIII if you insist on recording audio directly to the device.
