What is the difference between an interval and a chord?
A chord is made up of three or more notes played together or as an arpeggio (playing the notes of a chord in a specific pattern). In general, the notes of the chord come from the notes of its scale. An interval is the difference between two notes and is one of the building blocks of music.

The French augmented sixth can resolve to either V or a tonic six-four chord.

Which is the best augmented 6th chord for modulation?
The German sixth is the most commonly used of the three and works well as a pivot chord for modulation. The typical modulation you see is where the augmented 6th chord is built on the flattened submediant in the existing key and then leads to the dominant which becomes the new key.
