Would you still recommend it to someone who didn't like Stanley Parable? I must admit I found his prior game to be extremely boring and pretentious, but I'm willing to have an open mind about the new one if it's different.
There's definitely an element of personal taste, though—I tend to really dislike media that I find overly philosophizing (i.e. when I feel like the authors' arguments are too confident, or otherwise discourage the audience from thinking themselves about the arguments or conclusions). That is to say, I might be precisely the wrong target audience for this sort of game :-P
The intention of the game is to analyze this and ask why the narrator is so confident and dogmatic and to see a layer underneath, it's not to take the narrator at face value.
It's a walking simulator though, if you're not into those kind of things in general then you're probably not gonna be into it.
You definitely won't like it. The Beginner's Guide is much more in that direction than Stanley is.
I still really liked it, though.
