Neither one is great.
The first isn't great in either strength or agility - you need one of those to be decent for your offense.
The other is small and lacks stamina - he'll go down in just a couple hits or last just a couple round before tiring out.
You could consider taking the first to have a glad to experiment with and sell him when something better comes along.
There are "how to" guides for building rage/war/theatrics if you check out the forum. They give a good idea of what to look for and what to consider with your build.
There's also a "Should I get this slave" thread stickied at the top of the newbie forum where you can ask questions like this instead of starting a separate thread.
