Hedera Colchica Dentata Variegata or Sulphur Heart

I'm debating which of these to put in my garden. Growing conditions for both plants are the same and apart from the colours there seems to be only one difference and that is the rate of growth.

Some sources say that Sulphur Heart grows quicker and because of this I'm leaning towards buying this one but I do like Dentata's colouring more.

Does anyone have experience of growing both and does Dentata really grow at a slower rate than Sulphur Heart?
