I agree.  From a real quick comparison of the 16F882 and the 16F1938.

it looks like except for the number of Cap Touch Channels (11 for 882, 8
for the 1938), that each and every component of the 882 has a matching or
enhanced counterpart in the 1938.

Agreed here too. The accessible stack, linear memory, double the number of
FSR/INDF register sets, and the 14 additional enhanced instructions are
just the tip of the iceberg in terms of improvements.
