I’d say you might get pro-JUC responses given this is the cartier board. Personally, between the 2 I’d choose the VCA, but wear it on its own. Both bracelets are beautiful, and I love the look on the website of the small JUC with diamonds, but really don’t care for how you get it on. I own two 5 motif VCA bracelets and there was a slight learning curve taking it on/off (and I need to use a bracelet tool) but I don’t feel like I’m straining or warping the bracelet like I did with the JUC. The small JUC was also quite thinner and less of an impact than I expected on my 5.5” wrist.
My next bracelet I’ll probably consider the next size up JUC since it opens easier or the Bvlgari Serpenti with a similar look and easier way to take it on and off.
