Got given a ThinkPad P15v (upgraded to 64GB RAM) as my work development machine. It's heavy, it runs absurdly hot, and it chews up the battery - an hour with IntellliJ open is very optimistic. Got a ThinkBook 14-IIL (16GB) as my own personal machine - hugely prefer it even for development work, much easier to carry about, battery lasts for hours, doesn't seem any slower in practice.
They both seem pretty robust and they both run Linux perfectly, but unless you absolutely need need need a discrete graphics card or loads of ram I couldn't recommend the Pad, and they are damn expensive for what they are. Book on the other hand - great machine. Crap for games, but excellent in every other regard.
