The first one is the standard 'easy-up' hood - which is what I have on my 8. If the sides are on, putting the roof up or down can be done in less than 2 minutes.
The second is the traditional roof (with multiple studs to pop on) on a shortened windscreen - if Brian is around, he can talk you through this as he has this. Looks fabulous.
I prefer the look of the second, but like the practicality of the first.
