I'm working in IT and I get all new machines for our company over my desk to check them, and I observed the exact same points as the OP.
The new machines are either fast and loud and hot and with poor battery life, or they are slow and "warm" and have moderate battery life.
But I had no business laptop yet, ARM, AMD, or Intel, which can even compete with the M1 Air, not to speak of the M3 Pro! Not to speak about all the issues with crappy Lenovo docks, etc.
It doesn’t matter if I install Linux or Windows. The funny point is that some of my colleagues have ordered a MacBook Air or Pro and use their Windows or Linux and a virtual machine via Parallels.
Think about it: Windows 11 or Linux in a VM is even faster, snappier, more silent, and has even longer battery life than these systems native on a business machine from Lenovo, HP, or Dell.
Well, your mileage may vary, but IMHO there is no alternative to a Mac nowadays, even if you want to use Linux or Windows.
