OK so here's the night question, what would Suzuki have to do/change to see you back on a busa?
I don't know a specific thing to answer that. They definitely need to get in the game technology wise. The plastics on a Gen II Busa are unnecessarily difficult to take off and install. That was by far my biggest complaint with the Busa. Heck, I don't even have to touch the plastics anymore to change the oil. Check this out... The filter and drain plug are right there.
There's really no single thing that I think makes the 14R an overall better bike. It's a collection of small differences and refinements that really add up.
The next Busa needs more tech, more power, and better brakes. I think everything else is left to individual opinion.
