As a beginner, I would use a driver with slightly more loft since most people who have just started struggle to get the ball up in the air with the driver. In my opinion, 10.5 degree is plenty these days since current technology actually allows the ball to come off much higher. Shaft has a lot to do with the trajectory off the ball flight also, e.g. a shaft with low kick point will launch the ball much higher than a high kick point shaft (Shaft flex and kick point is another can of worms....Most standard shafts are mid kick point).

If you have never really used woods before and you were to get something with 14degrees, I recommend getting a decent 3 wood as the loft starts from around there. (I have two 3 woods, 13degrees and 15degrees).

This way when you are comfortable with that, you can go out and buy a driver as you will most likely know if you naturally hit it high or low. I hit my shot quite high naturally and I cant really use anything with more than 8.5degree loft. Know how your swing is first before spending money as drivers can get very expensive. 3 woods are much cheaper.
