I've been through so many laptops. After I tried a desktop in 2019, I can't seriously consider a laptop, unless in a pinch. Even so-called "beefy" workstations, e.g. W series Thinkpads, I've returned. They throttle too.
You want to know what beats a $3500 Macbook Pro? For me, a desktop with "ok" parts and water cooling.
You'll never have a fan issue. You get to use high quality parts that are replaceable with their own warranty.
Even the cables are super high grade. And you still come in at a third of the cost, slightly more than half the cost if you want to splurge.
You'll never have slowdowns. You can power multiple 4k monitors, ultrawides, whatever you want.
It boils down to keeping all these parts in a small chassis. If Apple cared, they'd stop the soldering and add an inch and half thickness and let the thing ventilate, because these things are built for consumption, not creation (e.g. being under an intensive rendering/compilation/io workload).
