Compare feature classes

[JoseSanchez]

Hello everyone,

I need to compare  the same feature class from 2 different FGDB to find all the differences: new records, deleted records and updated records (attributes with different values).

How do you recommend to do that using Model Builder or Python.

Perhaps take a look here:  Feature Compare—Help | ArcGIS Desktop 

Compares two feature classes or layers and returns the comparison results. Feature Compare can report differences with geometry, tabular values, spatial reference, and field definitions
