the big difference is that Modellers-Resource work in ripping models and textures for models from games...
So far, there are models from all sort of games like:
Banjo-Kazooie
Sonic games
Mario games
SSBB
Final Fantasy Dissidia
Kingdom Hearts series
Pokemon (yeah, seriously)
Halo series
Star Wars
Evangelion (anime really, but still)
Pikmin
Sin & Punishment
and more...
Perhaps it could be of some help.
