Like you said, the manga skips two arcs of great importance and as a  result some events are modified (e.g. the first meeting between Touma and Stiyl after the first's memory loss), so if it is you first reading of Index, you should not read that but the novel instead, even because the manga has some spoiler cameos. Plus, the manga has terrible drawing. Anyway, the is has its pros too. for example there are some extra (seeimingly canon) contents (e.g. a flasheback of Index, Stiyl, and Kanzaki before Index's memory was erased), or some scenes that are only narrated in the novel and are absent in the anime are depicted there (e.g. Awaki's traumatic incident). Some volumes also have a drawing of Haimura. Obviously, these are minor stuff that can be found on the wiki or reading the manga online so them alone could not be worth the purchase. If you want to buy the manga, do it only for the sake of collecting, but remember to read it only after the novel and the spin-off mangas.
