I just received a pair of Trango Alps from OMC and am comparing them side by side to the Trango Extreme Evo Light. The Alps weigh less than the Extreme Evos, and are more soft and pliable. The Extreme Evos have a pronounced front welt, whereas the Alps do not. If you will do more vert ice and front pointing where a stable platform is key, you may be better off with the Extreme Evos.
There is a key difference in fit. For some reason, the thickness of the platform on the Extreme Evos creates a smaller toebox and reduced volume. My feet are cramped in these, whereas the Alps have plenty of wiggle room. In both, I am experiencing some heel lift (which I don't in Sportiva Glaciers). It been awhile since I tried on Trango Evos, so can't remember how the fit compares to Extreme Evos or Alps.
