Art Scroll siddur is good so is Kehot siddur(Chabad) & Koren.
I recommend any one of them.
I use the Chabad siddur while davening with my Chabad minyan... Yes, it is very nice... Artscroll siddur also has more commentary than the Chabad siddur we use.... Although the Gutnick Edition Chumash does have some very nice commentary.
