Photini currently uses pyexiv2 to access photo metadata. pyexiv2 is a wrapper round the exiv2 library. It has several bugs that affect Photini, it looks unlikely that it will ever be ported to Python 3 and development of it seems to have stopped.
GExiv2 is another wrapper round the exiv2 library. As of version 0.5 it appears to be no harder to use from Python than pyexiv2 is. Photini should probably change over to using it, once it is present in the repositories of more Linux distributions.
