GSI has, by my understanding, realized that by hard anodizing it can make the pot even thinner. HA-Al is often lighter than a comparably sized Ti pot, and significantly less expensive (I can't find the link I had where someone had a GSI and the SP Solo Cookset and the GSI set was lighter for the same capacity).
Once you get to the thin wall sizes, material heat transfer properties are pretty much meaningless, the one with the thinnest walls wins.
Note, there have been some recent advancement / reductions in Ti wall thickness so the weight advantage of HA-Al is disappearing. Also, other than the AGG 3-cup pot, no one appears to do a HA-handless pot SANS 'non-stick' coating. Which is sad because HA itself is pretty darn non-stick.
Ultimately, HA tends to be the best 'bang for the buck' and is kind of a sleeper product that few people pay attention to.
Note, this particular model is being tested over at BGT GSI Outdoors Halulite Boiler
