Both Tinder and Bumble are dating apps that have their own pros and cons. It all depends on one’s preferences. Asking which one is better would be equivalent to asking whether McDonald’s is better or BurgerKing. On a positive side, Tinder is far more popular and hence there are greater number of people on Tinder. On a downside, Tinder can also have a lot of non-serious people and scammers lurking around to trap people.
Hence, one should watch out. Bumble on the other hand being new, has a limited amount of audience which also means that you have a lesser competition there.
