Kentkleen has got there before me; but Stephen, the point is that Alex is just explaining that the Xinbo and CLX are of different material and that the SLX is different again.
And there is no "defensiveness" or "antsy-ness" - just a clear statement of fact as he sees it. A putting straight the record.
As I see it Alex is consistently a true professional as he takes the time to give a true comparison as he knows not just his but his competitors' products.
As mentioned above - it is the customer service which counts and that is where you will have to come up trumps - because all things being equal that; not even the unattainable perfection, is what will win you customers.
