Hi all, I am user of both octane and corona, but not a high quality visualizer as most guys in the forums. My opinion is that both engines are great and very fast. But you can't do direct comparison, it's just a matter of choice for the user, depending on more parameters, like the modeling application. If someone have the money for let's say 4xtitan cards or more I would bet on octane because I think the setup may be easier than a local render farm and you can have almost instant results . Octane's real time is looks a bit smoother but corona is new on this. On the other hand corona is very fast without the need to spend a fortune for GPUs+PSUs and there is the solution of cloud render farms for high end results.
Octane on my single 580 with 1.50gb ram was far outdated in comparison with corona on my i7 but then otoy did two things: the one was "coherent ratio", a mode that almost doubled the render speed and the other one was "out of core rendering" for textures only (they are loaded on system's ram if there is a need) . So now they are almost equal because I can do a clean 2k image in about 2hrs I think, in both engines and that gives me flexibility.
One funny thing is how less ram memory a scene consumes when you remove it from 3dsmax. I did a scene first in sketchup and then in octane standalone. It was almost 700mb in my gpu's ram. 3dsmax for corona took 7gb!
