Another case of "depends on your fingers". I find D to be one of the easiest chords to make because my first finger joint easily reverse-bends so I can cover those three strings while skipping the bottom one. It's as easy as any "one finger, one fret" chord for me.
Dm is the same. Two strings with the tip of that middle finger, and drop the index fingertip down on the next string.
Dm7... slightly more difficult. Dm, and drop either the ring finger or pinky finger down on the bottom string.
I guess I can do that reverse fingertip bend a lot easier than I can a forward finger bend... so, these chords are a breeze for me. But, any kind of barre chord that requires me to keep a finger STRAIGHT while bending the finger next to it. Well, it just doesn't happen! Not with any accuracy, anyway.
