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.
We all had external keyboards, mice, and multiple monitors on our desks. The only time we were ergonomically constrained was when we were mobile. But we could be mobile at a moment's notice, and with all our stuff still running.
Now what I really would like is a high quality, low latency complete remote system. I got pretty close to this with a recent experiment, but it took a good bit of effort (and I still had some weird issues). It was great in that I could go to any computer with enough power to drive a browser, remote into my server "desktop", and continue right where I left off.
If that could get perfected, I would probably switch to an iPad Pro with optional keyboard.
