I'll bet the Nexus Prime will change your stance about Samsung. Don't those Nexus phones get straight updates directly from Google?
Considering HTC's track record lately, I'm not counting on the Vigor being perfect either.
But the Prime (and the Nexus S) is NOT a true Samsung phone. Like you said Google controls the software upgrades. It's a Google phone manufactured for them by Samsung. One can not be compared to the other.
