Anecdotally it hasn’t been that hard. I’ve had the best luck with Linux Mint just working straight out of the box. I basically only use my computer to game so your mileage may vary if you need specialized software or something.
Also the benefit of mint is that Ubuntu has a huge user base comparatively so you can find a lot of info online for people who have probably already figured out issues that you might encounter.
