This is some great conversation going on here and I see a lot of what I have experienced having taught average users and beginners for several years now.

As with some comments, I agree, page builders in the right hands can be perfect, or a freaking nightmare. When Headway first came out I did my own site using it. Also, I know several beginners who gave it a whirl. For most it didn't work, for some it was a dream come true. But who really took it and ran with it was the designers, and I see that happening with other page builders.

Is this the perfect answer for everyone? No. Is it for the average user who wants more control over their design? No, not in all cases. Is is the perfect tool for designers who don't want to learn code? Yes, in some cases.

As with anything there are just so many variables. And I think as designers, or even just average users, all need to weigh the options. And to be honest, I have found that page builders, especially the ones that are more heavy weight with options and controls are overwhelming and a large learning curve for the beginner DIY'er or typical user. Out-of-the-box usually works best in those situations.
