DTI vs DSA barrel for AR build

[Ditch-Tiger]

I am in the process of building another AR and have the opportunity to trade an R4 contour DSA barrel that I have lying around for a pencil profile DTI barrel.
Both barrels are non Chrome lined 1/9 and although I'd rather have the lighter weight of the pencil profile, I'm not sure which is the better or more accurate prone barrel.
Thoughts, specs, opinions and first hand knowledge of either barrel brand is welcomed.

The barrel profile is the most meaningful difference between the two. If you prefer the lighter barrel, make the trade. I would do the same in your shoes... I love pencil barreled ARs. That barrel could make a very fun lightweight plinker or walkin-round-the-woods gun.
