Why is the CO2 in this 80W rated at 2000-4000 hrs and the other 80W tube is rated at 8000hrs+ ?
Because the lifespan of a laser tube depends on the amount of current and power used. If you keep using the highest power, its lifespan will decrease. But if you use the lowest power, its lifespan will be extended. 2000-4000 hours are calculated based on 60% power.

From The Internet A CO2 laser cutter can engrave wood, plastic, and metals, including stainless steel. However, a CO2 laser cannot engrave the metal directly as the laser beam reflects from the surface. In order to engrave stainless steel, the material must first be pre-treated with a marking solution such as CerMark or LaserBond.28 Sept 2021
If special processing is used, the engraving effect will be improved in some cases, and what you said is also correct. But still not as good as pulsed laser machines.
