KanColle is the ultimate F2P gacha game and nothing beats KanColle for it.

You can have every character in KanColle as they will eventually come back for drops. You can get any character you want if you overprepare yourself with resources (and a lot of your time if your luck is bad) absolutely for free. I think the hardest character to get so far is Graf and I hope she is available as a drop again soon. Now the only problem with KanColle is buying slots if you're purely F2P and want to collect them all, but 10 dollars for extra ship slots isn't that bad.

On the other hand, if you want a particular character on a mobage, are you ready to pay up? If not, don't bother. Mobages are designed to steal your money after all. But I think GBF had gotten a lot of flak for bad gacha rates that they improve themselves over time, especially with the monkeygate scandal that started the existence of sparking. I hope FGO actually improve their own gacha rates as well, although the switch from four quartz to three quartz for a single roll is a good step.
