I am using FreeBSD on my desktops/laptops since about 2006.
I work with Linux systems (mostly RHEL/SLES/Ubuntu) and some other UNIX systems daily and I still prefer to use FreeBSD for its features and simplicity. More about these here:

You can use for example ThinkPad X1 Carbon 6th edition for some more modern hardware. I really love this old 7-row classic ThinkPad keyboard so I use ThinkPad W520 from 2011 (last one with such keyboard).
Here is a list with FreeBSD laptops with various features tested:

I write and maintain my own 'FreeBSD Desktop' series here:

... but there are plenty of other such guides - just type "FreeBSD laptop" or "FreeBSD desktop" to get more howtos.
Regards.
