It partly depends on the personality of the hamster and their life before you get them. Some hamsters have been traumatised before you get them - in pet shops eg. And you know nothing about their genetics or parentage.
It's true Robos are harder to tame or handle

They are so fast and little.
Russian dwarf hamsters from pet shops will be hybrids. So even if called Campbells or Winter white, they will be hybrids of the two. Hybrids can be prone to diabetes and/or have shorter lives or other genetic defects. It's pot luck. They still make lovely pets, but it's something to be aware of.
You could try and get a dwarf hamster from a breeder, where they will have been hand raised, and partly tamed already, you will know their genetic background and it will be possible to get a pure Winter White or Campbells.
Or have you thought about getting a Syrian? Arguably they are easier to tame and more cuddly.
