Its quite like a spool, I run with a gear diff in the front with putty - you get the best of both worlds!
Faster entry corner speed than a spool, quicker exit speed than a standard diff.
On an out and out fast lap, the spool is still probably slightly quicker but much harder the drive, the gear diff is much more forgiving adding consistency in a race.
Gear diffs are not really being used in the UK but I was at a pretty big meeting a couple of weeks ago, i was the only person running a gear diff and ended up winning the event.
I'd never EVER go back to a spool!! EVER!
