The upshot of it, from what I know about it, is that 30mm. tubes will NOT significantly improve optical performance in and of itself over a 1-inch scope tube.  That is a function of many other variables, glass quality, coatings, etc..

 They WILL allow a greater range of windage and elevation adjustment, simply because they have more room for the internal optical elements to move up and down as well as side to side.

 All else being equal, a 30mm. tube is somewhat more ridgid (stronger) than a 1-inch tube, though that is seldom a real-world concern, assuming that we are comparing modern, decent-quality riflescopes.
 They are obviously a little bulkier and often heavier as well.
