<p>I have a Pentax K3 and love it mostly. I've been wanting the Canon 70D for it's touchscreen and flip screen and I got one during the black friday refurb sale and really love it too. The K3 is a fine camera, but I guess I'm a bit of a feature fiend and I love the idea of being able to touch a point on the touch screen and have the camera focus there and take a picture too. The wifi functionality and tethering is really nice too. The autofocus on the canon's with their silent focus is really much better than Pentax's screw drive and unreliable SDM (I'm looking at you 16-50mm).</p>
<p>That said, I'm probably going to keep both for now.</p>
<p>Briefly tried the Nikons, but I find their controls counter-intuitive, the Pentax is the best IMO. The Canon has improved and has been helped with the touch screen, but still has room for improvement.</p>
