I have both and the only thing I can say is I enjoy the different types of lighting (silly, I know). I can't say for you, but I use the Make a Wish Compilation almost every day - I have a small obsession and love for the Medieval era and Elves... if you see where I'm going with this it all depends on how often you would make use of candlesticks and treestump tables. I typically wouldn't buy an entire compilation for one expansion to the game (because you may not end up using it as often). Just think of your typical style and see if it would fit well. If it wouldn't, I'd say pass on it and just use the Supernatural expansion stuff. Make sense? It's all really up to you, but my opinion is I love the stuff in it because I use it in normal gameplay as well. (To be honest, I've never really used the compilation with Supernatural.)
It's my opinion, but I hope it helps!
