Well, things happened...
I originally bought a discounted x15 r2 for around 2k usd(12900h, 3070 ti), the thing needed to be repaired so much that when I asked dell for a replacement they eventually agreed to it, I got a maxed out 7780 (13950hx, 4090, 4k 120hz) out of it, and don't get me wrong, the thing is a great upgrade and feels much better quality, but since it has a smaller wattage than gaming laptops and doesn't allow undervolt, now im just wondering if I should sell it and get a gaming laptop, I have the same reasons you mentioned even, better cooling, more wattage, undervolt and cheaper.
That's why I wanted to know if there is a more hidden aspect in which a workstation is superior to a gaming laptop, since they are work oriented I suspected they were build to last more, but I'm not sure if that's the case.
