Universal join vs double join

[radugns]

The v4 version has the "new" universal join, but there double join is marked as be an upgrade, but also came on market before v4. My CVDs has some wear so I need to replace them, which is my best option?
Thanks and have a great year!

I really like the universals, they really are a fit and forget item, they are pre-assembled and the wear rate is low.
