I recommend people buying AMD where they can. Vermaden on Lobsters is a BSD expert. I asked them what hardware runs pretty much all BSD's. Vermaden narrowed it down to a few Thinkpads. All of them on eBay from recyclers had Intels. So, Intel just came with the box.
If building from parts or doing non-BSD, I'd go with an AMD, POWER, or ARM system.
All the ones I saw in good condition on eBay were Intel's. I got a T420 with Core i7 to mitigate potential slowdowns from future CPU vulnerabilities. I've occasionally had to restart it from suspend/resume issues. Otherwise, it's been great.
One more thing: the function key and control key are swapped compared to most laptops. I didn't like that because I'm used to control being far left. duclare told me about a BIOS setting that swaps them back. Everything's fine now. :)
