Any advantage using obsolete 85053A rather than 85053B verification kit?

I recently sent my 8720D to Agilent in the UK for calibration. I got it back a week or so ago. 

On the calibration certificate issued by Agilent:

I noticed the 3.5 mm verification kit used was the obsolete 85053A, not the current 85053B. Is there any advantage in using that kit over the current 85053B? I was thinking of buying a verification kit, so would like to know what's the best model to buy. 

I'm guessing the calibration procedure for the 8720D was developed before the 85053B was available, and Agilent see no reason to update the procedure to use the current kit when the obsolete 85053A does the job. But if there are advantages in using the obsolete kit, I'll bear that in mind when looking for a kit. According to the information I can find on the current 85053B it does support the 8720 series, so on the face of it, buying an 85053B would be a better choice.
