I went with the X2 because of all the positive reviews.
I haven't owned an X2, but have owned all of the others. Of the others, the Montana has been my favorite.
I like them all, but I am not as fond of the stock on the EW, Nosler, and 700 MR.
The Nosler is also a lot heavier than a Montana, and it appears to me that the X2 is the same. As long as weight isn't a big factor in your selection, the X2 or Nosler would be a good choice.
I plan to try an X2 in the future, in hopes that the stock is better than the others provide. They look like a really nice rifle, but not a lightweight.
