I agree that Chris is probably the most accessible for those who aren't skating fans. However, I'm not really sure that is a necessary consideration for the English language commentary provided by the ISU. The USA and Canada have their own commentators for their TV coverage. That leaves just the UK, Australia and New Zealand. It is not available on mainstream TV in the UK for casual viewers to 'discover' when flicking through channels - people have to deliberately seek out either the (limited!) online BBC coverage or the ISU youtube channel. Very few casual viewers are likely to stumble across either. I don't know about Australia and New Zealand, but I would be surprised if it was on their mainstream TV.
