From my experience it's better to use both laptop and workstation. When I'm normally working I use the comfort/performance of the workstation, when I'm on the move I can use the portability of the laptop.

Basically all developers I know have "hybrid work arrangement", working some days from home/travels and some from office. They all remotely connect to their workstation at work either from their home computer of from laptop when traveling.

Maybe it depends on type of development or age of developers, but I'm not 20 anymore and laptop is an ergonomic nightmare. If you want to use it for a longer period of time and avoid health issues you should get an external keyboard/mouse/screens anyway. Which means you just recreated workstation, but it costs more money, has worse performance and all kinds of issues while connecting so much stuff to it.
