Not rhetorical.I assume that's rhetorical since $1700 < $2000 and Apple fans automatically favor Apple stuff. If not, refurb is generally just as good as new, so I wouldn't let that tag influence my comparison. After that, it's a matter of looking at features & benefits and choosing which is best for you.
No one choice is best for everyone. For me, I landed on a Dell Ultra-wide 5K2K as my ideal Mac monitor. Others can only see the ASD as sole choice or it plus the Pro one with $1000 stand as the only choices anyone should consider at all (because everything else is obviously inferior, "wobbly" junk). Still others can be quite happy with a much lower priced 4K monitor... and just ignoring the "retina or bust" spin.
Read reviews, go see any that you can and let your own eyes & mind make the best decision. If you have an easily transportable Mac like a laptop or Mini, haul it to some monitor stores and hook it up to some demo units to see how macOS looks on them.
I have mostly used Apple displays. I used to research displays to find the best options back in my PC days, but have gone with Apple displays since 'designed for mac'. That said, Apple has not really kept up with all the tech available today, whether that is because they just choose not to, or because they have assessed it to not be up to the task or offer the value others say it does.
I am now contemplating replacing my Apple Thunderbolt display, which true to Apple longevity is still going strong, or so I might think until I place a new monitor beside it (As happened when I got the Thunderbolt display and realized how dim the backlight on my previous monitor had become.) Contemplating is the key term, for were it not for comparing the Thunderbolt display to the iphone, ipad, and MBP displays, I would not have any reason to even think about an update (for note - I spend more time on the Thunderbolt display than the other three)
So I am pondering whether or not the price of the ASD is worth it, not just from a features perspective, but from a longevity perspective. For a variety of reasons, I would prefer to spend more and have a longer lasting display then to be replacing it in a few years.
