I'm searching for an American phrase that would be equivalent to the British “X is great value for money”, one that’s not too colloquial and can be used in a serious product description.
I am aware of following phrases with my objection in parentheses.
- price-performance ratio (not frequently used)
- cost-benefit ratio (not the same)
- Bang for your buck (too colloquial)
- A great buy (too colloquial)
- bargain at twice the price (too colloquial)
The British version is neutral and can be used in a formal product description of a technical product for marketing purposes.
It may be the case that #1 is the best or only choice, but I wanted to canvas for other ideas.
