I'm not certain you can get anything other than conjecture with your question, as it only asks for opinion. If I may ask, what do you want to do with the laptop, once the GNU/Linux is installed? 

- IMO, certain distros are better for certain tasks. It depends on how you intend to use the device, right?..

Well, as I said in the post (though not very well I guess) I was asking about compatibility. Sound, video, touch pad, wifi, printing. In the past, the two areas where I've personally seen some variation in compatibility is audio (hardware) and printing (software). Touchpad also, but I don't care about touch pad - don't use it.

I prefer the Debian system because that's where I have the most experience. I also like OpenSUSE a lot, but I've had "no-sound" issues with SUSE on this laptop in the past. Also, it was a real pain to get the right driver for my Canon printer on SUSE.

I originally posted this in the Precision Mobile Workstation forum, but they moved it here. I think my post made more sense there because I didn't mean to ask for opinions about distros. "Experience and advice" from using Linux with this laptop, is what sums up my question.

I use Ubuntu LTS (24.04) and everything works well, even BIOS/firmware updates works.

I have Precision 5570 and previously 5530 and Ubuntu 20.04 was even Dell supported OS.
