I guess that depends on your usage patterns. I like the T1 (NVG compatible) & H1. I think the T2 is overpriced. For the price point the Aimpoint Pro is great (own one and I really like it) although bigger & weighs almost twice as much as the others. I bought a Trijicon MRO and I'm really liking it, great price, great optic although I am still waiting for someone to make lens covers for it.
