EDIT: The ratings are my opinion, but the downturn can be seen on goodreads ratings and is discussed in the WoT community. While not all agree there was a downturn, it being a point of contention in this series is an indicator there was one for most people.
For reference, the other series was Twilight, and I made it all the way through book three before I gave up in disgust at that waste of time. So maybe that means WoT is roughly twice as good as Twilight in my eyes? I'm not exactly sure that's high praise. Or praise at all...
It slows to a tedious chore, particularly around the Knitting Circle leaving Ebou Dar with the Aes Sedai. All that is pretty obvious grinding to quota from the author.
If you want some next level fantasy, check out The Malazan Book of the Fallen, by Steven Erikson. Few stories have so emotionally buffeted me. It is brutal, macabre, tragic; but also redemptive, funny, clever - dazzlingly imaginative.
It slows things down, but adds some nice visual context.
Ready Player One had a moment where for two full pages it was a literal comma separated list of pop culture references. It was one of many such lists although not normally so long.

In a similar vein, my anticipation of The Doors of Stone has gone from fervent to uneasy as the years have dragged on...
I just hope that George RR Martin doesn't keel over before he finishes his next book, and we're left with the incomprehensible hack job of the HBO series as the resolution.
The Wheel of Time was stupidly verbose and slow from book one. I really have no idea how the books became so popular. I think it was because Jordan was willing to talk to people online back when that was a thing.
If you simply focused on Mat instead of Rand's Tsundere Haremfest, you would have a good story and it would be 3 books long, tops. (I'm leaving aside Sanderson's seeming inability to write Mat's character properly.)
Yes it was sprawled out more by then, but at least the plot started to move forward again. I remember doing the math and for one of the PoV characters in book 5 (Rand maybe?) it was less than 48 hours for the entire book, much of which was him worrying internally about things mostly inconsequential to the plot.
I also really enjoyed the prior book, when Mat's luck runs hot leaving Tar Valon.
I said to a friend when I stopped that he would die before he finished the series. I didn't think it would be as soon as it was but I happened to be right anyway.
Picking Sanderson to finish it was smart. He knows how be ruthless with a subplot
Did he intend to finish? Probably.
Was he capable of finishing? Previous work suggests not.
