Single body vs Double-body regulator

Hi,

I'm looking into kegging, using a two-keg setup. The two systems I'm looking at are below:

Standard Kit ($209) - 3-gauge dual body regulator (Chudnow)

Premium Kit ($204) - 2-gauge single body regulator (Taprite)

My question is this: which is preferable, to have a budget dual-body regulator (Chudlnow) operating both kegs independently, or a better quality single-body regulator (Taprite) operating both kegs through a manifold?

I would "suspect" that the dual-body allows for more flexibility in charging kegs, allowing one keg to be at serving PSI while the other keg can be force carbonated. I dont think this is possible with the single-body regulator since both kegs will be operating at the same PSI through the manifold.

What is of greater importance, the quality of the regulator or functionality as an entry-level brewer getting into kegging?

I like having a dual-body, since it's not unusual for me to have a Saison and a mild on tap (or some other combination of beers that need to be carbed to different levels).
