A compromise of compression. PC has currently 20k statics, way beyond most games. We do optimize our video clips too for the same reason. Just a small quality improvement across the board would be catastrophic for our disk weight. It's the price we pay for "the flow", as I like to call it.
I won't dispute your opinion about Jes' work, I share it too. He is undoubtedly the master of HS1 light, and its most gifted animator in the AVN scene. Zanith is definitely in that conversation too. My strengths lie elsewhere. As do Lykanz's, frequently forgotten but easily the most well-rounded. Arguably though, it's a matter of preference and taste. I think all of us surviving HS1 artists are currently at a level at which we shouldn't look at each other to compete, but rather, to learn.
Regarding HS2, I'm partial to Cryo's studio work, I consider him the reference. Cari is not as focused on pure technical studio work, but he is a genius editor with a very sharp sense of pace and display rhythm. I'd be happy with just a fraction of it.
