I have Canon separate devices (scanner, inkjet) and have been very happy with them over a few years now.
My sister recently binned a HP multifunction device in favour of a Canon multifunction device (quite independently, I had no input!), as she didn't get on with the HP or its software.
There was a recent thread that had some negative things to say about HP software, btw.
I have long been a fan of HP laser printers, so I'm not anti-HP.
Sorry, bit vague I know.
