Pentax K-r (vs. Canon 60D)

I've had my Pentax K-r for a year now, it was the first SLR camera I have had, but I'm not sure I'm overly happy with it.

Has anyone else thought found that you can't control the settings fully manually, if you want to change one thing it changes another without you wanting it to and it never gets the exposure right?

I've found the Sv (sensitity priority automatic exposure) setting is the best to use to get the exposure right with less blurring(movement) but it still seems difficult if you don't have the flash on.

It is a pretty loud camera, both the shutter and the auto focus, and the battery doesn't seem to last very long.

It's probably just my bad camera skills and not knowing exactly what I'm doing, what all the letters and numbers mean, and how to use it properly.

And I'm considering getting a Canon 60D, what do you think?

ALSO I have this thread open too with more information if it helps you help me:
