Congrats on your anniversary! The Cartier love never appealed to me bc I like dainty jewelry and it seemed to stand out too much. When I saw the small love, I couldn't get it out of my mind! However, when I ended up in stores and tried both on, I almost went with the classic (for all the same reasons you listed). My husband ended up telling me to get the small one that I initially loved (and then reassured me that we could "upgrade" in the future if I felt like I made the wrong decision).
A year later, I love my small love even more than the day I bought it and can't believe I ever second guessed myself! It is small and discrete enough for me. I have a sweet alhambra that I don't really stack it with and very recently (and impulsively) decided to order a small JUC to stack with the small love, but I have enjoyed the small love by itself on my wrist. Totally agree with sticking with your gut and trusting yourself. You'll be so glad you did!
I’m also thinking about getting the thin in all 3 colours.. don’t want to regret my choice, so will think about it
