It depends on what and how much you're feeding. Pellets won't really make a difference in cleanliness, unless you're feeding more than the turtle can/will eat and the uneaten ones become waste. Ditto for veggies, and you can net out the pieces that aren't being eaten before they turn to mush.
Anything that falls apart quickly, however, if it's feed with any regularity, would most likely leave the water cleaner if offered in a separate container of water. I mainly feed in the tank, and to make things easier for me, I will feed messier foods just before the tank and filter are going to be cleaned (Would have had to clean anyway.)
When/if I do feed in a separate container, I have the water level just high enough so that the turtle can grab the food and comfortably eat. This is usually just about enough to cover the shell.
