I really think the Nikon HG needs to be in this list. Its right there with the other three options optically and ergonomically. The field of view is super wide and the bino is light and compact. Build quality is quite high, perhaps ever so slightly less than the listed options. Also, you should include GPO Passion HD. I havent held one, but people say it has the highest build quality at $1000, and better optics than the Conquest HD, which is very hard to do at that price. The only way to end up with the best for you is to buy and try all these side by side. Easier said than done, I know...
