From your initial pro/con list, it seems you like the LOVE a lot more, and that you were considering the Signature primarily as a yellow gold bracelet alternative... Based on this, I will say LOVE for sure!
If you want something under the radar, you can also check out Chaumet (the BEE series, which I personally don’t love but may be to your liking), Bulgari, etc.
You are definitely right that I like the love a lot more. I have explored those brands a bit but haven’t found something that appeals to me as much. I’ll keep looking!
