Kindle and Kobo pdf support is dreadful. They do not even do text reflow. IMO don't even think about it.
The best for pdf support out-of-the-box is Sony. Ask in the Sony forum about T1 / T2 pdf handling.
The Nook may be okay out-of-the-box and can be rooted to run 3rd-party pdf readers. The Sony can also be rooted and run apps, but is not as good at it as the Nook. However, rooting involves some level of technical know-how.
