Personally do not think you will do better than the standard Hobie sail. I have no personal experience of the others but acquaintances of mine do - apparently they are only any use downwind/across the wind whereas the Hobie sail allows you to sail upwind very effectively as well (though your ability to point upwind depends on your boat's ability to point as well - the Mirage fins help the Hobies to point - Turbo fins better than the smaller ones - the optional daggerboard improves the upwind performance of the Adventure markedly over the other models. However all the Hobie Mirage kayaks that I have tried will sail upwind using the fins/daggerboard as a keel).
Be aware, though, that sailing these micro yachts can be tricky for the inexperienced in anything other than perfect (relatively light and constant wind conditions and slight seas) and even the experienced get the occasional ducking..
. There are a couple of mods you can make to the stock boat to reduce your risk of a bath but even so personally I do not/would not carry expensive camera gear on my boat all the time. If I carry a (pocket) camera I keep it in an Otter box inside the boat and only get it out if the conditions are right.
Mods/considerations to reduce likelihood of a capsize include
1. free-running blocks for the sheet lead so that the sail can be de-powered instantly
2. optional sidekicks which turn the kayak into a trimaran - lots of people use them for increased stability when sailing - or get an Adventure Island...
3. daggerboard (Adventure/AI only)
4. a batten in the foot of the sail to keep the sail open when sailing downwind - this has the effect of reducing the rolling action of the boat which is exacerbated by the sail opening and closing when sailing downwind
5. roller reefing/furling - stow the sail or reduce sail very quickly if conditions deteriorate.
