Out of playing the first 3 G4U games, this one definitely has the most content, though honestly that's not really saying much. The main theme this time around is winter apparel, with a new townscape to take pictures with. The idols don't really have many poses with their winter clothes on and they all pick from the same pool, so picture opportunities are the slimmest as they ever have been in that mode. To make up for it, there is also a beach swimsuit option in this volume, so that's basically the entirety of volume 1 added in here as a bonus. I would say that's enough content to make this worth a try but honestly I still think the poses and control freedom is still way too limited for it to be worth a rec outside of anyone but the sanest idolmaster fans (me).
