The shimano mechanical front derailleur is capable of outshining several other products featured in this list in overall features for the price point. Shimano redesigned it to have a lighter shift action, increased frame and tire clearance, and to work better with chain lines seen on road bikes with disc brakes and shorter chainstays. It works for 2x11, for 3x there are the claris 8-speed and sora 9-speed groups on a road bike, if you require a mountain bike you should look at another range of groups. The more compact design doesn't come at a sacrifice of shift feel.
Shimano claims that the new link construction matches the force curve of the hand more naturally to reduce effort at the end of shifting. It includes a cable tension setting adjustment at the derailleur for a more precise and ease setup. It is great with all packaging and manual.

The ultegra di2 6870 front derailleur has killer features for the price point. If you are going to ride steep hills, say 10%+ grade, you may want the Long version so you can use the ranges of cassettes 11x30, 11x32 or even 11x34 to make climbing easier. The action is light and crisp, and is perfect every time you hit the button. This is compatible with the 6870 shifters battery etc.

The front derailleur brings arguably the biggest advancement over the previous generation. It comes with the same compact shape and a weight of just 104g, but the 9150 front derailleur isn't just a next step, it's a quantum leap in technology. The feature (which can be disabled and customized) simplifies shifting by automatically shifting the front derailleur in certain gear combinations to help the rider maintain optimal cadence and power.
The derailleur keeps the same unmatched shift quality and smooth performance even under the torque of previous iterations, but now introduces syncro shift customizable shifting.
