my last personal anectode with ubuntu is this: my company decided to setup our office as a remote-onsite hybrid workplace, so our working machines were moved to a rack elsewhere to be accessed remotely and the local machines were supposed to act as basically dumb terminals that can be used interchangeably by us

we develop on rhel, but since the local machines are just to access our dev machines remotely, support decided to install ubuntu because it "just works". turns out, since ubuntu does a lot of stuff its own way for no good reason, it broke under our network configuration (it's complicated) and no snap application could run -- so, no slack or firefox. not a great scenario for a workplace. in the end we decided to replace ubuntu by rhel and no longer had any issues

you're right that ubuntu might work flawlessly for you and that it might never break. but, it also might break in unexpected ways. i cannot reliably recommend ubuntu to a beginner because this risk might forever put someone off of linux
