I went through this last year and came out with the Trini HD. I love my 10x's. These are really really nice bino's for the price.
I just went through this last week- to the point where the guys at the Cabela's Optics counter would roll their eyes, and seem annoyed, again.
For me, it was between the Trinovid HD, Conquest HD, Vortex Razor and Swaro SLC. You hear great things about various manufacturer's warranty, but, personally I've never had to send anything back to any manufacturer for warranty work.
Truthfully, to my eyes, I couldn't really detect a difference in optics. It mostly came down to ergonomics- what fit my face better.
The Vortex was the first ruled out. It came down to the SLC vs the Trinovid HD. I liked the Swaros, but didn't see the value paying another $600 over the Leicas.
Just got my Leicas yesterday, and spent a lot of the day looking out over KC from my 7th floor office. They feel very solidly built, very bright and I like the neoprene binocular harness that comes with them.
All in all, I don't think either the Voretx or the Leica is a bad choice, the Leicas just felt better to me.
