Equal to none or Unequalled?

"Our service is equal to none!"

Oh, really? Well, I guess I'll go elsewhere.

I came across this gem in a client's writing today and I just had to comment.

The sentence as written means that the service is at the bottom of the heap. It literally says that the service is equal to no service.

What the client meant to say was that no other company can provide a service that comes up to my client's standard. It should have read "Our service is unequalled!"

English is a tricky language.
