EJs are different than IJs. It's due to Introverted Perception vs Extraverted Judgement, and which comes first.
IJs have Introverted Perception (Si/Ni). So, they don't make up their minds as easily as perception wants more information before applying it through Je (Te/Fe).
Whereas with EJs, who favour Extraverted Judgment (Te/Fe), they've may have made their minds up quicker due to the previous information that was stored through Pi (Si/Ni).
