As a new bowler, buying a ball is a tough road. Almost all the "popular" balls are going to be to strong for your ability, including the two you mentioned. This of it this way, would you buy a new Corvette or Ferrari for a new driver? Of course not, a new driver needs something that will keep them out of trouble, like a base level Honda Civic.
So, if you really want to buy a new ball, get yourself a Hammer Vibe(choose any of the current ones), Ebonite Cyclone, Storm Match Up or Tropical, Brunswick Twist or Rhino, Motiv Freestyle etc. Something in that price point. You are looking for a ball that is $100 or less before drilling.
Learn to repeat your shots and to pick up spares. Bowling will be a lot more fun and as you become a more skilled bowler, you will become aware of the equipment needed to fill out your bag(if any).
