Two lenses is an insignifcant sample. Totally irrelevant, and absolutely not a reliable basis upon which to make a judgment such as this.
OTOH, I don't particularly like Stigma products (as is well known in these here parts), but my dislike of them has been weaned through about 30 odd years of experience in photography, and through my evaluation of a number of divrse products made by them over that time,, through which I've found them to be of genrally inferior build quality, and where appropriate lesser optical quality.
And when I effectively ban a product from my choice list - Sony and Dell would be two such examples - that decision is based upon such issues as quality of product, and, if and when a problem occurs, the attitude I experience when bringing that problem to the fore.
If an organisation treats me with contempt, and if the senior management also treats me with contempt, - as with Dell - then they lose the opportunity to enjoy my custom.
Or if their pricing regime is treating me as if I'm an idiot - Sony and Maxwell are examples here - I carefully review other options for purchase.
Sony rarely get my business ...
