The Founding Titan can indeed control Eldians. However, because Attack Titan consumed the Founding, he now has that ability, albeit only when in contact with someone of royal blood.

The Colossal Titan is the largest Shifter and can rapidly construct/deconstruct his body, and let of the large quantites of steam, at a cost of his body mass.

The Armored Titan is covered in significantly hard plates and is presumably the heaviest of all the Shifters.

The Female Titan (pretty sure that ain't its real name) can crystalize her body and has a control similar to that of Beast Titan, although much weaker.

The Jaw Titan has uniquely powerful jaws.

The Cartman is... well... a cart. I guess that's useful somehow.

The Beast Titan can produce unique strain of Titans and can control them. He is also significantly strong.

The Attack Titan however, has none of these powers. Sure, due to consumption of the Founding Titan, and the strain of Armored, he is rather unique and quite versatile, but he doesn't appear to have any unique properties (although I'm pretty sure there are some).
