I voted both being terrible, but I don't buy used games for current gen hardware. So as far as that is concerned, it is a non issue for me. Needing to be online all the time however, would be a problem. Not so much at home, but I am someone who plays my Switch on the go. Part of what makes that option so viable is running the software natively, without the need for an internet connection. If I had to always be online, it would impact that aspect of my gaming greatly.
Having said that, one would have to consider game preservation. Unless these games were made eternally available via online store for download, not being able to go on ebay in the future to get ahold of games you may have missed would be a major hit.
So my answer is split...for current gen always online would be worse. For game preservation however, no used games wpuld have the potential to be worse.
