I never used the one mentioned here, but I don't think a disk sander is
any where near as good as a TS in getting dead square and parallel
edges. Disk sanders are good at sanding curved edges. IMO, if you
aren't getting good edges off the TS, you need to tune up the saw...

OTOH, disc sanders are the bees knees for miter joints, not just curved edges.

I've used it on miter joints more than once, but I don't think I'd call
it the "bees knees". If your saw is set up correctly, you generally
have no need for a disc sander to fix miter joint problems. The main
secret to TS miters is preventing the wood from sliding when cutting, so
sandpaper on the fence of your perfectly made miter saw table is a good
idea.

Personally, I cut a lot of miters with my H.C. Marsh miter vise (subsequently
sold by Stanley as the #100 miter machine https://www.ebay.com/i/123109187472)
and a backsaw. So cleaning up the cut on the disc sander works well.

"perfectly made miter saw table" sounds expensive :-). My 25yo Delta
chopsaw isn't perfect by any stretch of anyone's imagination, but works
well when building fences and doing construction (nowadays I keep an
abrasive blade in it for cutting unistrut and EMT).
