G rank MHFU was definatly harder in general, but MH4U's G rank goes to levels of difficulty beyond most of the things in MHFU. Guild quests and to some extent apex monsters are the hard parts.

I do think that more buddies in MHFU helped more, you could quite easily spam traps and flashbombs and otherwise lock the monster down. Doesn't work that well in MH4U due to the monsters becoming resistant.
