Quickly by-passing Jeff Fortson's review, I'll add mine and see if they are close.
I think there are some similarities with both Landmark courses by mixing up the two nines with some natural features of the site. (This doesn't mean that they are anything alike in estehtics or design--they aren't. It means that the two nines have a different look to them.) The Palms utilizes natural mesquite on the front nine and closely planted palms on the back creating these "chutes" like teeing areas. It actually gives the flat site some interesting features that just really didn't exist when it was a date orchard.
The 1st is a unusual by C&S standards medium to long par 4, as most of their designs feature a short 2-shotter to start things off. The one-shotters are the best in their resume, and featue back to back par 3's at 16 and 17. Its quirky and fun seeing how they fit into the site, and the 16th is supposedly a copy of Riviera #14, which, if it is, on a much smaller scale.
The bunkering style of the course is clearly Brian Curley imitating George C. Thomas, which means it is too deep and a little too much. Still it is pretty challenging and it is well placed.
The 5's are pretty good, even the odd 6th which in truth needs a tad bit more defintion in the same way Bandon Dunes #18 needs a line of definition.
The greens are the typical C&S partly-crowned "Lays" potato chips, and they are challenging, but repetiticious. There are some pretty interesting faux creeks installed for a "Augusta-like" feel.at holes 7&8.
#18 is the best finishing hole C & S have ever designed, but that isn't saying much.
Is it a Top 100 Modern?
Looking at some of the courses on the list, yes, absolutely.
