I have the JUC diamond head, Pave + Onyx Bracelet, and regular Guilloché (not pave) with matching 10 motif. Here are my thoughts:
JUC is great and edgy. I love how simple it is to put on and take off. Very easy to stack with pretty much anything. Sometimes the nail part gets caught on clothing, especially when getting dressed or undressed.
All motifs 100% will flip, it’s just more noticeable on the Pave. I’ve been wearing the Pave + Onyx almost regularly since I got mine last year. I have a little trick to get it stop flipping - I just twist a couple motifs over twice, making the bracelet essentially “tighter”. I did have the bracelet shortened, and of course I could shorten it more for an extremely snug fit to completely stop the flipping, but then I wouldn’t be able to put it on and remove it myself - which is important for me.
Do you think you would ever wear your 10 Motif + 5 Motif together as a 15 necklace?
If yes, I would go for the Guilloché + Pave first.
I generally like completing sets before moving onto something else. I also personally enjoy seeing the shine of my Guilloché and my Pave on my wrist

Both bracelets are stunning in their own right, but nearly impossible to compare since they offer something different.
If you know you will add both pieces to your collection eventually, the question becomes, which piece do you see yourself enjoying more until the end of this year? Which piece lights you up when you think about wearing it during summer and the holiday season?
I hope this helps, and I will be looking forward to seeing what you decide
