Tempered glass, rims and the dishwasher
Many hospitality series are made of tempered glass. It is heat-treated after forming, which makes it cope better with thermal shock and with knocks. The difference you notice is at the rim: a tempered rim chips less quickly when glasses knock against each other in a full washing rack. That is why these glasses last for years in a bar.
All series can go in the dishwasher. If the glass does turn duller over time, it is usually limescale from hard water rather than wear on the glass itself; a cycle with vinegar or a lower detergent setting helps. Stand glasses upright in the rack and do not stack them inside one another, because two glasses that suction together rarely come apart without breaking.
