OK, saw both bags at Adorama. The measurements on the Tenba site are WAY off -- the bag is much smaller than listed. The Tenba Medium Shooter is actually smaller than the Thinktank Accelerated.
So, which to value more? The protection/security offered by the travel dedicated Thinktank bag (ability to lock zippers, tether entire bag with security cord, etc.), or the many useful camera-oriented features of the Tenba (but no security to the bag at all -- openings everywhere allow access to the inside of the bag). This is going to be a tough decision...
