I'd recommend Memory, Sorrow and Thorn by Tad Williams as being closer to LotR. It reads better, it's much more concise, it's a better story. The world feels more like Middle Earth too.
But the point about the middle dragging is true. Books 7-9 in particular are terribly slow.
I would read something else. Sure, each book might have 100 pages that are good, but you have to sift through 400 pages of Robert Jordan's, um, boring obsessions to find them. The first book is great fun, the second is decent, the third is mediocre. I thought it would pick up in the fourth and fifth book, but it just got worse. Every time Jordan writes a potentially exciting hook - for example, the main character discovering artifacts of great power - he discards it in favor of page after page of grouchy, frigid women fantasizing about spanking each other and grown men acting like junior high kids trying to get their first kiss. And don't get me started on the dresses and tile patterns.
When the terribly slow portion of the series is 2300 pages long, I think that's enough to say the thing's got a real problem.
I think the next real fantasy book I read after LotR was The Sword of Shannara. I had read R E Howard's Conan and Kull stuff prior to LotR. I read as much SciFi, maybe more, back then as well as standard fiction (mostly short stories). At some point after Shannara, when I got to reading some more fantasy, it included the Thieves World books and a lot of Eddings, though I was more partial to the Elenium series than the Belgariad stuff. I was never able to immerse myself in The Wheel of Time though I have the first four on my shelf and suspect I'll take another run at them someday.
I only read the first two books, but found them to be incredibly immature and felt that they were just Lord of the Rings with a cheap coat of paint.
Shannara, or WoT? That certainly sounds like Shannara to me, but not WoT.
