Anti-logic at its finest.
Oh yes, I do quite an intentional stretching in my conclusion=)
However my primary question is still valid - where is the "victim"?
Yep, that mentioned by OP "Exploration" of the surface features that has been killed by Odyssey?
I have no intention to defend Odyssey on that matter, to be honest - there is a load of related bugs and issues, some of them probably solvable/fixable in future, but some others are part of the core of the new mechanics, yes.
Probably I've just seen too many threads discussing dullness/sameness of the planets in Horizons way before Odyssey? Icy - Rocky-Icy problem, all that? And I don't like the that tendency of the modern myth creation on the base of Horizons, "dream that was killed".
Just for analogy - one could zoom,and zoom, and zoom in Mandelbrot's set, admiring the results and saying "Wow! Ahh! Uhhh!". But at certain point - sooner or later - the feeling of the sameness of that "diversity" is pretty inevitable. With all that zooming you are still in that same Mandelbrot set. In terms of elite this could be translated to jump-honk-FSS/supercriuse-... - about the same, but way more time-consuming. Or one can conduct a little experiment - log into Horizons, visit a couple of the nearest systems with 30-40+ bodies, go to system view, filter the most common lanbdable body class, pass to planetary view, get a couple or more screenshots of each body of that type from different views, store and mix the results in one folder, then browse them and try not to became bored up to toothache... (and once again, I do not state that in Odyssey it will be anyway better, more even worse).
Yeah, I could be subjective, but already for years the planetary exploration for me relies mostly on "external factors": events, friends, POI's - both procedural and handplaced - storylines and own narratives - and not on planet generation mechanics on itself.
Now, more technical part, about some Odyssey planetary tech drawbacks I see
Absence of planetary - or continental - scale features that we became so habituated to in Horizons. All those half-planet long canyons, a bit grotesque mountainous ranges... Probably with the exception of those copy-pasted mega-impact craters =)
Another candidate could be all these notorious and repeatedly observed patterns. However according to my own observations those patterns do no give any real idea about the underlying landscape. They are linked more to terrain coloration, could be probably affected by spawning of certain terrain tiles types (I'm far not sure in the latter) or - probably - to some low-frequency low-amplitude landscape perturbations that are hardly recognizable at close range. I mean, they are more the source of confusion in an attempt to judge the underlying terrain than practically helping in prospecting particular planet for any interesting landscape "features".
The above is understandable if we take into account that the main effort of Odyssey planetary tech is seemingly concentrated around "fine details" in order to better accommodate the environment for on-foot perspective and scale. And all these fine details are indistinguishable when viewed from the orbital distances.
However with the "fine details of landscape" we have the same problem of tiles/copies. Yeh, it's not so rare that from one peak of a mountain one could see another very similar just in few kilometres. They will be not
exactly same looking due to blending with another features, but still quite recognizable (the same applies to mega-craters that do look identical from the orbital plane - they are not exactly same "in situ", but - once again - recognizable as having exactly same origin model).
