If you’re expecting the same type of reliably you’ve from VMware on Proxmox you’re going to have a very hard time soon.
Try upgrading a v6.0 or even 6.5 ESXi from the command line. If there is no “enterprise” iLO or iDRAC or whatever with media redirection then you’ll be jumping in the car. Or what about if, back in the day, you went ESX instead of ESXi? lol!
How often do you find yourself repairing a vCentre? Oh dear the SSL certs are fucked again, despite being fixed a few years back. Yes I can bring the bloody things back but I’ve also got longer Linux experience than VMware. Those 14 virty discs were a daft idea and let’s dump the logs to all sorts of random areas and then stir them around every few versions. … and its 400GB in size - even thin provisioned they are still huge for what they do.
How about when the Dell customised .iso was the only way to install on Rx10 hardware and then made the box unupgradable years later? or when the Intel NIC drivers got a bit confused - yay - PSoD?
Reliability: don’t make me laugh!
I’ll drop this: https://www.techradar.com/best/best-linux-distros It’s written by an actual journo and not a bunch of nerds in nerdville!
Getting into Linux is a bit like Windows back in the day - interesting and a lot of fun … and rather nerdy. My first Windows version was 1.0 and my last was 7. Mind you I do run a MS Silver Partner and worry about a lot of Windows servers and desktops but my daily driver is Linux.
Mint is a great choice, even though it isn’t mentioned in the article I linked because you get a great community, which is pretty important. Its basically Ubuntu and therefore Debian too, so a lot of howtos will work.
I personally rock Kubuntu but I have a requirement for enterprisey stuff - ESET and Veeam and AD integration and all that. I also get Secure Boot out of the box and not all Linux distros work with that.
Your smart new laptop will have Secure Boot enabled so you will have to deal with that if you deploy a distro that doesn’t. So with say Arch, you will need to turn it off or learn how to sign your kernels etc and that is not a beginner topic! I suggest you turn off Secure Boot if your chosen distro doesn’t support it, rather than insisting on it. Its a nice to have but not the most important security feature ever.
You might want to show a bit of ankle and try out a few to start with. Most distros have a live CD that you can boot and try out first. I suggest trying out Mint, Ubuntu and Kubuntu. That gets you three modern interfaces to play with.
If you are into gaming then it kooks like Pop!OS would be a good place to start instead.
There is no real best option - it’s what suits you and you have choice.
