At this level, your starting to split hairs.
All scopes will perform very well, with no winners unless the seeing is extremely good.
This is going to be a decision the atmosphere and weather is going to make.
Like having 3 supercars all together for a race and its raining.
None of the cars will be able to reach its best performance, so you will have similar results.
If you cypher thru it on paper, theory or use computers and wave analysers then you will get definitive results. But unless its going into space, forget these reults and look at what is possible with human eyes and local atmosheric conditions.
The vixen with corrective lens's improves flatness and other abberations, the RC has none to start with, but you can add them as an option, and then its a whole new ball game again.
They will all have a near perfect view in your eye, and do some excellent imaging, so it boils down to how excellent do you want it, and will you notice the difference easily.
