Which of these carabiners will hold more weight before it fails?
I'm getting started on slacklining. While the shape of an oval carabiner seems ideal for the pulley system that uses 4 of them, I don't know if an oval carabiner will hold the weight. Between these two, which is the better choice for slacklining, and why?

If its just the weight you are worried about then either will be fine. Look at the first products back bar - there is the normal information tagged to it giving its breaking strain if pulled in two directions. It gives it as 23kN. This roughlly equates to 2300kg or 2.3 tons. You will not be able to create that force through slack lining. In fact you wouldn't be able to make that force even if you fell onto it at terminal velocity.
If you turned them on their side then the carrabiners go to a third of their strength and so too will they if the gate is open.
If you had to pick one of them for their efficiency then I would probably go for the first one. It has a smoother rounder finish to allow slings (tape in America?) or rope to pass over them. The second is more designed for fixed knots.
Or, if you wanted to go the whole hog, get the HMS screw gate (http://www.rei.com/product/782699 from the same company) as this has the wider bar at one end but is still smooth.
All of them, no matter what you choose, will be strong enough.
Hope this helps.
