69 Front clip

I am looking for a new front clip and am hoping to find some input.  What type of quality comes with this new tube like framing?  As I have been shopping around I have noticed that some of this tube framing is cheaper then normal frames.  Is there a big difference in quality of design or is this strictly based on the type of metal used?
 
~Thanks for the information~

The original frames are weaker/heavier than the tubed ones, also they are updated to easily accept most suspention upgrades.

So tubular framing is def. the way to go?
