Docker or Native Ubuntu

[artincube]

Thank you both for argumented opinions.
I am relatively new to both Ubuntu (but with decades experience on MacOS, understanding of bash/zsh scripting, I feel quite at home for the most part) and Docker (I have managed to deal with the storage and networking aspects,, compose and more).
I have to say I am very impressed with Docker after a few weeks experimenting. And when I broke things I just killed the containers and rebuild etc as bitmap suggests. So I think I'll build in Docker for peace of mind. And I kind of have the feeling the laptop will not last very long, so indeed the migration to a new machine is something I expect in the next 2 years at most.
The only thing I do not understand well, still, is the GPU part. Even on Ubuntu I've had a lot of trouble with the proprietary drivers (Nvidia 650M in my laptop). It seems to work now but I haven't investigated if its potential capabilities are used either in Ubuntu or Docker.
