I saw you asked similar question in tree frog section and want to see which one would be better fit for you. So i will run down some about both. None of amphibians like to be touched by the way.
If you like cute and easy, go for american green tree frog that you said they have in store. Downside of this - you need a forest looking bigger sized tank with vertical space. You can also go all out and make naturalistic vivarium for him. So you will have cute and pretty. These frogs are not as demanding as pacman frogs, but still you will have to provide proper environment.

Pacman frogs are different kind of cute, most are aggressive eaters and you need to keep respectable distance while from their mouthes lol these frogs require complete substrate change once a month, temps and humidity has to be always spot on, feeding and supplements while frog is growing as well has to be spot on. Pacman fogs sometimes are called rock pets, they will sit in one spot and wait for food, they grow big and fat tree frogs will be active at night, for pacman frog you need smaller tank, you will not be able to keep 2 pacman frogs in one tank, but you can keep multiple tree frogs together provided they are similar size and same species.

If you say you have a tank - what tank do you have, because it may be suitable for one or another, but cant be for both
