Hello, welcome to the forum. Pacman frogs are great and easy to care for after you get everything stable husbandry wise. But if you want a frog you can watch and actually see these guys might not be for you. They spend the daylight hours hidden under the ground and come out at night to eat. As a baby they will chase food but once they get bigger they are more of a sit and wait predator, you need to bring the food to them. I don't know much about tree frogs because im a horned frog type of guy but some of them can be very active and more bold if you want something like that. Again I think a lot of the tree frogs are nocturnal but they actually move around the enclosure instead of sitting in one spot when they wake up. And frogs are no touch pets but some of the tree frogs like whites will tolerate it every once and while were as a pacman doesn't really like it at all, and he has teeth so if he chooses to bite you for bugging him you are going to feel it. Were as the tree frogs will just gum your finger to death. Again I love my horned frogs but they aren't for everyone, but if you don't mind a frog that you wont see a lot and wont do much these may be the guys for you. My biggest piece advice I could give is what ever way you choose to go you should try to have the enclosure up and running with everything in spec heat and humidity wise for a couple days so your not tinkering with things while hes in there. The first few days of relocateing to a new home can be very stressfull itself for a frog and when someone is around the tank a lot those first few days it really adds to the stress and makes the settleing in a lot longer.
