Currently you can pick ninja or summon you want to get (provided its in current event cycle) and good chunk of power in addition from fukurokumaru.

Old fuku format forced random and nearly useless ninja (with the exception being gamariki and edo deidara back when he was meta) with pretty much same choice of spending options.

Overall you are forced to spend on good ninja anyway, but instead of lets say 30k worth of pure power items you got 10k and 20k as useless frags. New format is better for sure.
