Can only comment on the Charmoz properly, although I tried the Trango on at the same time and discarded it in favour of the Scarpa.
I liked the Charmoz for scrambling and easy climbs. It's a fantastically light boot, and has a narrow toe box which I found useful for wedging into cracks when on more technical ground. I liked the "climb zone" flattening on the front of the sole; some may feel its a bit sales gimmicky, but I felt it let me feel the rock a bit better than a cleated sole might.
Given the narrow toe box I didn't favour it for extended trips; after my third day walking in them my toes were feeling pretty pinched. My major complaint, though, was that they didn't last long. I went through mine in 11 months of moderate use on the usual mix of Scottish rock and bog (never used them in the snow). The silver textured material which they've used for the sides of the upper wore through, and eventually I was stamping about in wet feet. The soles, too, weren't much further behind. I'd caveat that by saying that I am hard on boots, and these were the first pair of lightweight synthetic mountaineering boots I have bought, and they taught me the tradeoff between weight and durability.
I have a couple of mates who also have the Charmoz. One had the same experience as me, the other's have lasted better a lot longer than mine.
Hope that is of some use. One other to look at might be the Mammut Monolith ?
