5 speed or 6 speed

[carphotographer]

Couldn't actually find an answer so what's better to have a 5 speed or 6 speed gear box ?

I'm considering in buying a Caterham, or another Elise, I've had two already and love the Elise but thought I'd try a Caterham.

It would be interesting to hear from people who've had both
