Is the otter box defender series worth it?

I had an otter box defender series for my iPhone 5 and I liked it but the screen protector over it would prevent me from touching the screen. I d have to apply more force. Now I have the iPhone 6 and am thinking about the otter box for that but I still fear the same issue. And some reviews I have read say that the buttons are hard to use and the touch ID doesn't work good with it. Right now I have a ballistic case which is comfortable and I like it I just wanted something more protective. Should I stick with the case I have or get the otter box?

The Ballistic Hard Core case for the iPhone 6 provides better protection than the Otterbox, and the screen protector fits very well. It's a much better case than the earlier Ballistic cases. So if you want maximum protection, get another Ballistic case.
