The Primal Land is great. Though be warned: It's written with a more Clark Ashton Smith flair than Lovecraft or Howard. Situations and events are often meant to be satirical or tongue-in-cheek, rather outright serious.
As a matter of fact, the first story in the Primal Land sequence is a send-up of Conan. In this case we get to see how a Conan-character would appear to civilized folk -- a drunk nasty, violent, narcissist.
Given that though, the stories are entertaining, evocative and good inspiration for adventures. Definitely some good S&S.
There are also Lumley's Dreamlands novels, which is pure S&S in Lovecraft's Dreamlands. Great stuff as well.
