Another thing you have tothink about is this.
With the larger blocks, you have more room to "CREATE" With all the stunning blocks that are coming out now, it is harder to creata a good looking block while still having it preform well. At least that is the way I look at it. I am a form and function kind of guy. I like things that look and preform good. But hey what do I know?
