Scott,
I bought a 60" First Choice and am very happy with it. I can't say it's the absolute best on the market because I haven't seen every box blade on the market. I do think it's got to be the best for anywhere close to the money, however.
I didn't look at Gannon, for example, because I knew the price was way out of my league. For that much more money I hope they'd be superior in some way. Even if you can afford it, have you asked yourself if you really need the absolute best one on the market? What do you intend to do with it?
As to mine, the best way I can describe what I bought is that I got better than LandPride quality with superior fit and finish for close to a King Kutter price. Best of all, I got it painted to match my tractor (JD green in my case) at no extra charge. /w3tcompact/icons/smile.gif
They do that, Kubota/Kioti orange, Ford/New Holland blue and red for about everyone else. I posted about mine and even included some pictures if you'd like to see the fit and finish up close.

I hope this helps.
