This is a personal opinion of mine, but of the two mentioned it would be the Knight TK2000 for me. I have read too many posts about how well these shotguns perform. I have a friend who lives for turkey hunting. He uses a Knight TK2000 because he claims he gets better shot patterns at longer ranges with it, then him modern smokeless shotguns. He must do something right because he kills lots of turkey. One he claimed at over 40 yards, dead on the spot.

Also Knight provides a video and a great manual for most of their weapons. I see no reason why the Knight would be any different. I was going to go the same route as you, but instead went to a traditional side lock Thompson Center New Englander 12 gauge which I am still waiting on...
