A couple of unboxing type videos for the 18-disc blu ray box set of ‘The Skywalker Saga’ (they should give an indicator of the quality of the box itself, disc housing, contents, etc. In the UK they are £60-65 / $74-80 US):-

I have not found a review for the 9-disc DVD box set as yet. (in the UK they are around £40-45 / $50-55 US.):-

^ The 9-disc DVD box is indeed somewhat different to the 18-disc blu ray box.
For those of us in the UK… Argos has the two ‘Skywalker Saga’ box sets - for £40 (DVD), and £60 (blu ray).
It is apparently available in the US too (these box sets are labeled as being ‘Region Free’ - but best check first):-
https://www.amazon.com/Star-Wars-Skywalker-Complete-Blu-ray/dp/B082WXD4ZH - $149.99. It may be cheaper and also available elsewhere?
Edit: and here - https://www.amazon.com/gp/offer-listing/B082WXD4ZH - through 3rd party sellers; the cheapest at $132 US.
Also… https://chipandco.com/star-wars-the-skywalker-saga-dvd-box-set-now-available-for-preorder-381212 - it refers to a pre-order at WalMart for $130 for the 18-disc blu ray box set (though the link to the set at Walmart is now broken).
The same here too - https://comicbook.com/gear/news/star-wars-the-skywalker-saga-box-set-is-now-available-on-blu-ray

^ so it appears there were plans for the 18-disc blu ray box set to be released in the US - but for some reason it has been delayed or shelved?
