The 763 CIP– with the new, lay-flat business seats– is fine. It's not nearly as nice as the 77W (773), and I'd prefer a different aircraft over this one if scheduling and routing allowed.
That said, the business seat is fine. It's not the most comfortable for sleeping, and the footwell seemed fairly constricting to me. It's much less private than the 77W or Club World on BA. As a solo traveler, definitely take a window seat.
There's very little convenient storage around the seat. The tray table is quite large.
The big advantage is all-aisle access.
This plane doesn't have an entertainment system built in, but they pass out tablets (and noise cancelling headphones).
Row 7 is missing a window. 8A is often blocked off as a crew rest seat.
