The reason why you don't like it is because it's way too blurry. Look at the gray circle between the 1st and the 2nd/3rd/4th panel, see its edges? Bad. See the edges of the round gray stuff in the 3rd panel? Also bad. What the whole page in general lacks are patterns. You blurred so much that it all became unicolor (more or less, you didn't fix the bright streak mark in the middle of the last panel) and that's what makes it look off.
Benii's version is better in that regard, you can see all those horizonal line and dot (see car seats) patterns which make the page look a lot more natural. Though, of course he didn't do any manual work on his page, so it's riddled with hard black noise that you got rid off in your version.
So yeah, no, you didn't lose that much detail per se, it's the pattern detail that you lost that makes the page appear like a korean web-manhwa instead of a printed manga that's been scanned and edited. Personally, I really don't like that plastic look, so I'd recommend applying more "Strength" (move up that slider to like 0.9, depending on your method, do that twice or w/e) in an effort to preserve more patterns. And just in general, apply less filters, since in this case, less is literally more.
