I have a couple of Eotechs (517 and a couple of EXPS3's) as well as a couple of Aimpoints. Of the five...I have no preference as to handling and usability between any of them, except for the T-1 which I don't care for at all (4 MOA blob, internal reflections, small diameter tube).
As to weight, an XPS weighs about 30% less than a PRO.
