Well the questions is which one does one prefer, not which one is more high end. So my answer is, I prefer Tiffany. I just like the designs better, and I find them more wearable.
Cartier also has many beautiful pieces and is definitely more high end. I like their watches, and the Love and trinity collection. But most of their other stuff I find are too much for me.
But from my experience, Cartier does have better customer service. Tiffanys if you go upstairs to the bridal section you will also receive excellent service. But on the ground floor it really varies from store to store.
