I have owned both, and compared them side by side. I prefer the O/96 and now in my 7th year with these speakers.
However 0/93 speakers are much easier to get right, easier to place, easier to find amp match etc, easier with room sizes. O/96 is more finicky, it took me a long long time to find the right room/amp/placing for these speakers (years...). But they are worth it and are IMHO end-game speakers unless you have stupid-money for uber-speakers (and they might still not necessarily beat the O/96).
I am very curious to hear from people who have upgraded from O/96 to O/Bronze or the limited edition O Twenties, but guess it's still early days.
