Usually its good idea to have 4 girls of Gold+ rarity that are above lvl 50, post evolution, to carry you, while you can fill in the rest with other lower tier/lvl girls.
What I did was first lvl up most of my Golds, then swap in silvers and bronzes to ride the exp train.
Event missions give bunch of EXP, and also the GS equivalent of manyu missions do actually give some of the best EXP farm for your characters (horrible player exp though) while additionally dropping the manuy spirits which can be further used to lvl up.
Its very efficient to run these as much as possible and combined with manual upgrading via the spirits you can power lvl you team rather quickly.
