The only problem I have with MHG is the lack of content, it doesn't even have G rank, but even so it has my favourite monster, armour set, soundtrack and playstyle so far, I love all the details they added in this game and the hunter arts are REALLY cool. I wouldn't say you should skip over MH4U because there's a lot to do in that game but I would also say play generations because it's very well done plus you get to play as palicoes :3
