Need an assist here - looking for an everyday road machine likely to use often for Zwift and quick club rides. For the sake of argument they're the same price and both in excellent condition.

The contestants are:
1) Restored 1992 Bob Jackson 531 with Dura Ace 9000 (11sp)
2) Serotta Concours titanium with Dura Ace 7800 (10sp)

What say you?
