The B-2's only advantage is it's "stealth" capability, which, as the article states, is only useful in places where the US hasn't established air superiority. Once they have, then the B-52 would be superior "mission capable".
The B-52 only has room for 51 500 pounders, The B-2 hauls 80. Except for the ability to externally carry some of the older technology cruise missiles externally, it cannot haul more stuff than a B-2. The B-2 will carry 192 of the new LOCAAS autonomous miniature cruise missiles, that have a 70 mile range and search out their own targets with a ladar.
It is not a bad aircraft, but the the B-2 is superior in every way. Comparing the new generation of aircraft and miniaturized weapons now hitting the battlefield is like comparing WWI to VIETNAM. It is THAT much different, and better.
I'll let you in on another secret, 60's muscle cars ARE NOT faster than 2006 models.
The B-2 hauls more stuff actually.
