I think Donkey Kong Tropical Freeze is a masterpiece. My favorite game of this decade after Dark Souls.
3D World is also great, and my favorite Mario game after Bros 3 and 64.
The biggest defects of Tropical Freeze are that Diddy's ability is similar to Dixie's, but not as good, you can only play as the other characters who arent Donkey Kong in hard mode, and the bonus levels are repetitive and not a lot of fun.
The biggest defect of 3D World is that the levels seem to be distributed randomly.
You dont have water worlds in which all levels are water inspired, or snow worlds in which all levels are snow inspired, you have any kind of level in most worlds except the Bowser ones, because of that the game doesnt have as much personality as Bros 3. If you think of World 3 and remember the Sun enemy, you easily deduce it was in World 2, the desert world. It is hard to remember in which world a level was in 3D World.
