ISFP vs ESFP
Common ground
ISFP and ESFP share S, F, P. Beyond the letters, both may value purposeful conversation and enough room to form an independent judgment.
The real divide
The practical divide is priority. ISFP responds to the present through personal values and a strong sense of what fits; ESFP engages with present opportunities and checks them against personal values and their effect on people.
How to tell them apart
ISFP and ESFP can look similar when the setting rewards the same behavior. To separate this pair, watch what each protects when time, certainty, and social pressure pull in different directions.

Agree on when exploration ends, who decides, and what evidence would justify revisiting a decision.
How they differ in relationships
