Hi Zhiliang,

This page:

http://gmod.org/wiki/GBrowse_adaptors

is a start at answering your questions, but is probably not enough.
The two loaders are for two different database adaptors that can be
used under different circumstances, thus the different in table names
and contents.

The Bio::DB::GFF adaptor has been around longer and works well with
GFF2 data; the bioperl scripts that works with it are bp_load_gff.pl,
bp_bulk_load_gff.pl, bp_fast_load_gff.pl. Bio::DB::SeqFeature::Store
works best with GFF3 data, and the bp_seqfeature_load.pl script works
with it.
