Tempered glass option is glossy but with a panel of glass in front - so more reflections + potential for dust to be trapped.
I'd take matte personally, it is a very light coating and gets of of the vast majority of reflections. And my personal theory (I can't really back this up) is that the brightness level makes more difference to the "pop". Glossy may look ever so slightly sharper, but in that case I prefer the mate coating and lower brightness as it is easier on the eyes (and looks more natural, but that part's subjective).
Definitely doesn't look worse.
