Yea it's good enough. I'm using a 27" 4k with my Mac, scaled show the same amount of stuff as a 5k would, so 125% I guess. Sure it probably looks worse than a real 5k monitor if I was to pixel peep, but it's great to me and I don't think 5k is worth the more than 2x asking price.

Scaled resolutions work much better than they used to. For example the iPhone 12 Mini scales at 2.88x by default and I've never heard anyone complain.

However I think it might also depend on the specific panel. I have a Lenovo portable monitor which is 1080p at 14", and running it at anything except 1x looks absolutely awful.
