First of all, I'd like to say that I use the Artscroll Machzorim for Rosh HaShana, Yom Kippur and Pesach. This machzor however tries to cover too many Yom Tovim (Succot, Chol HaMoed Succot, Hoshana Raba, Shmini Atzeret and Simchat Torah). You end up flicking pages forwards and backwards too many times. In my opinion, you are better off using the standard Arscroll Siddur and buying a guide to Succot.
One more point. Do NOT!, I repeat DO NOT use this machzor in Eretz Yisrael. There are simply too many... more info
