Display Mount

I have two auria 27" monitors. Planning on getting an articulating mount for them. Would I be better off getting two single mounts or one dual? Was thinking two singles may allow more flexibility than a dual being as 27" is about as big as most mounts support.

I have been looking at the VIVO brand on amazon and they look to be good any first hand experience here?

no recommendations at all?

I love my ergotech mounts, u can slap on multiple arms on the pole if you want to.
