Dr nick or hans moleman???

Ya I have the same line of thinking so far.. I might even prefer hans I'd say! but I think I'll hold out until the update to buy one just in case something new comes in that I really want haha.. A girl has to keep her options open after all :D

Hans is worth getting cos he cheaper get nick when u can :) I've got both and they much of the same really, personnally I prefer Hans :)

what is nick like, task-wise?

Here is a list of all the characters with their tasks:

Hans is a great character to have around town, but I am liking Dr. Nick. He has some funny lines.

I like dr nick much better just for his sayings alone. (I guess that only matters if you play with sound on, otherwise moleman's short film task is better)
