best path for continued progress for a eldrich knight

Using an aasimar a level of fighter and sorcerer for early entry into ek. At 12 level what class would be good option for continued spell level and bab concerns. Dragon Disciple looks promising but would like to hear other options for other people.
Thank you for your responses in advance.

A lvl of Paladin will probably serve you better if you have at least 14 Cha. Even once per day, Smite is a great asset.

The same goes for a Gendarme cavalier. Never mind about the mount, you get challenge once per day + power attack as a bonus feat like a fighter would have.

After EK continue with Hellknight Signifer

Another interesting option is replacing the martial lvl with one lvl of Oracle of Battle. You qualify with the skill at arms revelation and you get access to lvl 1 divine spells. Couple divine favor with the trait Fate's Favored and you have a fast +2/+2 attack and damage bonus. Then, after EK, continue with Mystic Theurge. You will end up with CL18 arcane and CL 9 divine. This is probably your best option.

Do not forget to take Magical Knack (Sorcerer) too.
