I, personally, think Dwarf Hamsters are great if you want a small pet, and much cuter than the bigger Hamsters. Dwarf hamsters are easier because they don't require a really big cage, they don't need to keep getting bigger wheels with their growth, and they don't need as big portions of food.
I found this information based on my experience with hamsters, especially with my pets, and from websites and pet store advice.
