Sorry, my bad!
No worries.
in Dutch TV commercials, comparisons will never mention the competitor or its products by name, while in the US there are countless "coke vs. pepsi" commercials, for example
Like Jono I've noticed a few examples in the UK over the last few years (superstores and banks, mainly)... I might be wrong but I think there used to be rules preventing explicitly mentioning the competition in advertising until fairly recently.
If you look at the examples (superstores and banks) you should note that it's possible to objectively state that X's prices are lower than Y's, or that A's interest rates are higher than B's - they're essentially being no bolder than stating facts. Quality, on the other hand, is not so quantifiable... whether A's customer service is better than B's is a matter of opinion, and as the Trading Standard hoo-haa shows, it's consumer opinion that ultimately matters.
Where the OP is concerned, a feature comparison is basically fact-based ("We have X, Y and Z whereas they can only offer X and Z") so I don't see the problem as long as you don't get too carried away with the descriptions (especially as it's probably not even an advert, technically). That said,
tooting ones own trumpet doesn't always backfire and the 'Darling Special' is ripe to be taken to the next level by someone brave! (
