Mintedbaby claims to be "the #1 FREE Sugar Daddy Dating Site". Well, it is true that the site is free. But I am afraid that the title of No.1 is untrue.
Mintedbaby does not have a good Alexa ranking, which means that the site is not very popular. The design and look of the site is a little bit of simplicity. There are some problems of form disorder which is caused by misused CSS.
Inside Mintedbaby, things are quite simple. The site only offers the basic features as a dating site. Most of user profiles are simple too.
Anyway this site is free. You should give it a try without losing a cent.
