Halinski glossy/coated models

I've spotted some Halinski models which are coated/glossy. After reading some comments here in the forum, I understand that glossy paper is harder to work with. Is this the case also with these Halinski models or only an issue if self printing a digital model?

So I think the real question I have is that does the glossy models require so much more additional skills & practice that a beginner like me is just wasting money and should just go with traditional matte model and possibly just use a glossy varnish instead?
