One thing I'd add to this discussion is that right after geo frame tubing/construction is the next most important thing in how well a HT rides. While geo is free...tubing, an amazing design and quality manufacturing are not.
I don't disagree, but I think you also have to factor in the relative value and cost for this ride quality. For me geometry is a very clear #1, somewhere in the very distant #5 and #6 is frame material and design/ride quality (#2-4 for me is suspension, brakes, and tires)
As you've mentioned frame flex/ride quality is going to be largely subjective in this category. My weight, riding style, and expectations of what a HT should deliver will likely vary greatly from yours. For me, I know I'll get a more discernible improvement in ride quality with a 27.5x2.8/3.0 rear tire, much more than any inherently engineered-in ride quality could deliver. This is what makes HTs so fun IMO
When I went from the Honzo to Rootdown BA, I'd be hardpressed to note any improvement in ride quality, though the geometry and fit improvements were significant. From the Rootdown to Primer, no discernible differences aside from the Primer having an occasionally creaky PF bb interface. I moved to a Specialized Fuse to try and gain a bit more overall versatility, I really noticed and enjoyed the lighter weight but I also realize that I probably went too far in sacrificing geometry. Once again the ride quality was not notable, for an aluminum frame that was stated to be 'more compliant'. From the Fuse, I eventually settled on my current NS Eccentric Al which gave me 95% of the geometry that I liked from my Chromags (with a longer CS even which was something I wanted), in a more weight efficient package, at a killer price -- it hit my light/cheap/performance trifecta. The NS now sells for $480cdn including Canadian shipping, but out of stock currently. If you look at the NS' SS and CS junctions, they are not elegant and they are overbuilt. But once again I have not found the ride quality to be worse (or better) than anything else I've had previously.
