Mostly syntax. Mode objfpc disambiguates a corner case for procedural types
with an extra @ for assignment of procedural types, and a few other
tightenings.

The proponents of mode objfpc make a big deal out of the differences, but
IMHO it is mostly nitpicking. And worse unnecesarily incompatible
nitpicking.
